The reactions between Co(C10[subscript4])[subscript2].6H[subscript2]O or CoCl[subscript2].6H[subscript2]O, NaBH[subscript3]CN and some monodentate (PPh[subscript3] and Pcy[subscript3]) and a series of bidentate phosphines of the type Ph[subscript2]P-(CH[subscript2])[subscriptn]-PPh[subscript2] (n = 1-4) and also cis and trans Ph[subscript2]P-(CH[subscript2])[subscriptn]-PPh[subscript2] have been studied under a very wide range of experimental conditions. The reactions are affected by (1) the amount of NaBH[subscript3]CN used, (2) the rate of addition of NaBH[subscript3]CN, (3) the temperature, (4) the solvent used and (5) the reaction time. A number of cyanotrihydroborato and other complexes have been produced and others observed but not yet isolated.
