Transition metal hydroborate complexes. IV. Cyanotrihydroborate complexes of the group Ib metals

The synthesis of several copper(I) and silver(I) compounds containing tertiary group V donor ligands and a coordinated cyanotrihydroborate or cyanotriphenylborate anion is reported. Complexes of general formula L3M(NCBR3) are shown by physical measurements to contain metal-nitrogen bonds, both in the solid state and in chlorinated hydrocarbon solvents. In acetonitrile solution [(C6H5)3P]3Cu(NCBH3) is a weak electrolyte, as determined from conductivity studies. The relative extent of dissociation of hydroborate and chloride ligands from triphenylphosphine-coordinated copper(I) ions in acetonitrile is found to be B3H8- ～ H3BCN- > BH4- ～ Cl-. The cyanotrihydroboratotris(triphenylphosphine)silver(I) compound is more highly ionized. From its infrared spectrum, the complex of empirical formula [(C6H5)3P]2Cu(NCBH3) is concluded to be a dimer, with bridging cyanotrihydroborate ligands coordinated to form both Cu-NCBH3 and Cu-HBH2CN type linkages.
