Spanish abstract El compuesto bis(mercaptoimidazolil) hidroborato calcio, [BmMeBenz]2Ca (THF)2, puede obtenerse por reacción de Ca(BH4)2•2(THF) con 1-metil-1,3-dihidro-2H-bencimidazol-2-tiona. La difracción de rayos X demuestra que los ligantes de [BmMeBenz] se coordinan de una manera κ3-S2H de tal manera que el calcio presenta una coordinación ocho con una geometría dodecaédrica que presenta dos interacciones Ca•••H-B
English 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 κ3-S2H manner such that the calcium is eight-coordinate with a dodecahedral geometry that features two Ca•••H-B interactions
