Molecular Graphics

Custom molecular graphics programs CHEM-RAY, CHARON, CAP and PROJECT have been developed here by Professor Joseph W. Lauher. CHEM-RAY, CHARON and PROJECT have been incorporated into the TEXSAN software package and are available for purchase from the Molecular Structure Corporation.

Sample CHEM-RAY images are shown in the following selections:


Recent Results from the Molecular Structure Laboratory at SUNY Stony Brook

Molecular structure determinations of organic, inorganic and organometallic compounds are carried out on a routine basis. CHEM-RAY pictures of some recent results from the Molecular Structure Laboratory are shown below:




The crystal structure of the urea of aminohexanoic acid. This view shows three layers edge on. Each layer consists of a beta-network of molecules held together by hydrogen bonds. This molecule was synthesized and the structure determined by Dr. Leticia Toledo, a postdoctoral student in the Fowler/Lauher research group.

Color Codes: (C-turquoise; H-white; N-blue; O-red)




This molecule is the lithium salt of a tripodal amine synthesized by Dr. Lutz Gade of the University of Wuerzburg and members of his research group. The structure was determined at Stony Brook by Professor Joseph W. Lauher.

Color Codes: (C-turquoise; H-white; Li-green; N-blue; Si-purple)



A tin sulfide from the laboratory of Professor John Parise. Structure by David Nellis.

Color Codes: (Sn-red; S-yellow)
