Abstract

Abstract: A series of complexes of the type (n-Bu3P) Co (DH) 2 (5R-tetrazolate)(DH is the monoanion of dimethylglyoxime; R= CF3, CH3, CsHs, C6HsCH2,(CH3) 2N, 4-FCtjH4, and 3- FCtjH4) have been prepared and characterized by conductance studies, elemental analyses, and'H,'3C (1H], 31P {1H1, and I9F NMR spectroscopy. Quantum-mechanical calculations (MIND0/3) indicate that the NI nitrogens of the aromatic tetrazolate anion are ...
