Synthesis and Structural Characterization of [BmMeBenz]2Ca(THF)2: Ca•••H–B interactions in a Sulfur-Rich Coordination Environment

Neena Chakrabarti, Patrick J. Quinlivan, Gerard Parkin

Abstract


The bis(mercaptoimidazolyl)hydroborato calcium compound,[BmMeBenz]2Ca(THF)2, may be obtained by the reaction of Ca(BH4)2•2(THF) with 1-methyl-1,3-dihydro-2H-benzimidazole-2-thione. X-ray diffraction demonstrates that the [BmMeBenz] ligands coordinate in a k3S2H manner such that the calcium is eight-coordinate with a dodecahedral geometry that features two Ca•••H–B interactions.

Keywords
