摘要

The crystal structure of one of the simplest organoboron compounds, trimethyl borate does not appear to have been determined hitherto. The compound is of interest for the study of pi-donor ligands and their interaction with the pi-acceptor behavior of trigonal boron and the consequences of such interactions on molecular structure. We used powder neutron (with isotopically labeled material) and X-ray diffraction to determine the crystal structure of trimethyl borate at 15 K and 200 K (neutron) and 200 K (X-ray). The material is hexagonal (Z = 2) with a b = 6.950(8) angstrom and c = 6.501(3) angstrom at 15 K. The unit cell volume is 272.00(1) angstrom(3). The space group is P6(3)/M (SG 176) at 15 K and 200 K. This is the first crystal structure solved on the Neutron Powder Diffractometer (NPDF) at the Lujan Center.
