Have you StruMM3D a molecule today?

We pronounce StruMM3D like “strumm 3D”, or, better still, “strummed”. Indeed, we use it to reveal, display, and examine, the sweet molecular music that nature plays, and the currently available version is the best ever.


StruMM3D was used recently to uncover new information about the ferrocenes and ferricenium ions.


Recently StruMM3D has been rated as - “Awesome, easily the best molecule viewer/modeler of all time. The information StruMM3D mines from diffraction (XYZ) data, and molecular models, is most impressive.”

StruMM3D version became the first, ever, molecular mechanics program that enabled the user to examine every aspect of a transition state structure. StruMM3D automatically identifies transition state bonds, even in x-ray crystallographically determined structures, so that no human-generated connectivity tables are ever needed. This is a boon to molecular voyeurs and crystallographers alike. All chemists will be delighted by these new features in StruMM3D, especially since the transition state models can be systematically modified to reveal energy trends.

From the release of version, users will enjoy the full capabilities of our prized data file conversion utility FILECONV, for zip, nada, free. So go ahead, just launch StruMM3D, load any file of coordinate data, from most molecular modeling suites (CSD, PDF, CIF, XYZ, MOL, etc.), and you'll have a structure to examine. Unless, of course, the targeted data file has flaws, which is common because they are so complex, unlike StruMM3D's files.

StruMM3D version marked the successful attainment of one major step in StruMM3D's quest to finding global molecular energy minima, and new code for calculating bond orders. Version featured a re-worked algorithm for the automatic detection of functional groups, better program stability, and more conservative memory/energy usage.

The release of StruMM3D version marked an important milestone. This version sported a new colour scheme for atoms, which carries more structural stereo-electronic information. Re-designed working windows, more crash-proofing protection (from bad data and ill-advised user input), and faster graphics rounded out the list of obvious improvements. There are others too, but we can't elaborate here.

Many theoreticians boast that their computer modeling method/tool will generate good simulations of organic molecules, but their methods cannot, and do not, inform the user of some of the basic stereo-electronic features of these molecules. So these simulations are just not scientifically useful to someone searching for information. Imagine looking at the x-ray crystal structure of a transition metal complex in which the metal has 7 ligands. Can your molecular modeler help you to determine what the oxidation state of the metal is? Is there any way to even ask this questions using this molecular modeler?

In StruMM3D version the advanced structure recognition algorithms used will enable you to examine any transition metal complex, with any coordination number, to identify the oxidation state of the metal, and hence to identify one electron single bonds in that complex. Since transition metal based catalysts are now very important reagents in organic chemistry, your molecular modeler of choice ought to be StruMM3D, if you really wish to understand how these catalysts work. StruMM3D not only generates excellent molecular simulations, but it also reliably and transparently informs the user about all of the stereo-electronic features in the molecular model.

Bliss! Version has passed all tests in Windows 8.1, with flying colours!

StruMM3D version will boast some newly developed structure recognition and manipulation algorithms that have never before been implemented in a molecular modeling program. In particular, these developments will greatly facilitate the simulation of organometallic compounds. This new sophistication will enable users to easily perform molecular modeling studies not easily done in the past.

One thing became painfully obvious during our testing of StruMM3D in Windows 7/8, the UAC feature of Windows 7/8 is of questionable utility, and might simply be ill-intentioned.

So why does Microsoft use the UAC feature to try to frighten users away from programs they did not develop, and now designate as from an “Unknown Publisher”? Is the user only supposed to use programs published by Microsoft? And then, even some Microsoft programs generate the "Unknown Publisher" annoyance. The only people that benefit from the Windows 7/8 UAC are Microsoft, and its satellite companies that try to milk small software developers in order to digitally sign their software. The UAC is a Microsoft scheme to crush private software developers. So, just re-assert your independence from these monopolists and turn off the UAC feature. There are excellent anti-virus and anti-malware programs around, especially within the Windows 7/8 OSes, and so the chances of a careful user unintentionally executing malware are miniscule in today's computing environment, , unless you habitually ignore your computer's anti-virus and anti-malware programs warnings.


StruMM3D is, now, really ready to reggae.


Update Your StruMM3D program

StruMM3D tells you when a newer version is available so that you can get it. However, if you haven't updated your StruMM3D recently, go download and try the newest version of StruMM3D. It will be faster and just awesome! Remember to visit the StruMM3D FAQ for hints, user/program tips and additional help.

Users of versions of Str3Di32 must update to StruMM3D, which has total backward compatibility with all Str3Di structure files. Current users of StruMM3D should download only StruMM3D.ZIP and unzip it into their Str3Di folder/directory, to apply all recent updates.


If you're not using StruMM3D, then why not?

If you regularly review structures that have been determined by the diffraction methods (x-ray crystallography etc.), then you simply MUST use StruMM3D to visualize your data. StruMM3D is the ONLY molecular modeler that enables you to spot weird bond lengths, among other oddities, that find their way into diffraction studies. Serious crystallographers always use StruMM3D.

Do you want to see how good your current molecular modeling program is? Or isn’t. Then we dare users of other molecular modelers to see how quickly they can complete one of our very routinely done molecular modeling tasks. This one involves using your current molecular modeling program to spot flaws in the coordinate data of published x-ray crystallographic investigations. Try it.
