CHAKRABARTI, Neena; QUINLIVAN, Patrick J.  e  PARKIN, Gerard. Synthesis and Structural Characterization of [Bm^MeBenz]₂Ca(THF)₂: Ca•••H-B interactions in a Sulfur-Rich Coordination Environment. J. Mex. Chem. Soc [online]. 2017, vol.61, n.2, pp.90-96. ISSN 1870-249X.

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 κ3-S2H manner such that the calcium is eight-coordinate with a dodecahedral geometry that features two Ca•••H-B interactions.
