MRI: Acquisition of new single-crystal X-ray diffraction system for teaching/research laboratory

Tatiana Timofeeva, New Mexico Highlands University, DMR 0420863

The first in the US laser system for crystal growth on diffractometer was used to crystallize and study several liquids, such as metha- and ortho-nitro toluene, ethyl acetate, methyl benzoate , diethyl carbonate , and to study their molecular and crystal structure.

Porous structure of MOF with coordinated water molecules (green) inside, and (b) hydrogen clusters formed inside MOF.

A highly stable porous lanthanide metal-organic framework, Y(BTC)(H2O)·4.3H2O (BTC = 1,3,5-benzenetricarboxylate), with pore size of 5.8 Å has been constructed and investigated for hydrogen storage. Gas sorption measurements show that this porous MOFcan take up hydrogen of about 2.1 wt % at 77 K and 10 bar. XC-ray crystal structure of material was studied at NMHU and neutonografic investigation was carried out at LANL. Neutron powder diffraction data revealed four distinct D2 sites that are progressively filled within the nanoporous framework. Junhua Luo et al., JACS, 2008, 9626.

In spring 2008 four NMHU students graduated at Chemistry Department. All of them used crystallography as a main tool to study synthesized mate-rials .
