Crystal structure of (2,2′-bipyridine-κ2 N,N′)-trans-bis(tert-butyldimethylsilyloxy)-cis-dioxidomolybdenum(VI)

Abstract

In the title compound, [( t BuSiMe2O)2MoO2(2,2′-bipyridine)] or [Mo(C6H15OSi)2O2(C10H8N2)], the MoVI atom has a distorted octahedral environment with the siloxy substituents occupying the trans positions. The complex contains a rare (R 3SiO)2 MO2 (M = Mo, W) structural motif and was formed in a reaction between sodium molybdate and tert-butyldimethylsilyl chloride in the presence of 2,2-bipyridine. In the crystal, neighbouring molecules are linked by C—H...O=Mo hydrogen bonds, forming chains propagating along the a-axis direction.
