Abstract
The triethylborohydride anion [HBEt3](-) transfers intact from Na[HBEt3] to a calcium center to form the monomeric organocalcium complex [Ca(HBEt3){1, 2,4-C-5(SiMe3)(3)H-2}(thf)(2)], which is stable in solution and the solid s tate; the [HBEt3](-) anion is coordinated in a multidentate fashion to the metal, which likely contributes to the failure of attempts to abstract the triethylborane moiety from the compound.
