摘要
Cobalt(H) complexes of the general composition CoLX2 {where X = Cl, 1/2 SO4, NO3, and SCN; L = 2,3,8,9-tetramethyl-1,4,7,10-tetraazacyclododeca-1,3,7,9-tetraene [N-4] (DAED) or 2,3,8,9-tetraphenyl-5,11-dimethyl-1,4,7,10-tetraazacyclododeca-1,3,7,9-tetraene[N-4] (BDAP)} have been prepared. On the basis of electronic and EPR spectral studies, the chloro, nitrato and thiocyanato complexes were found to have six-coordinate, octahedral geometry and the sulfato complexes were found to have five-coordinate, trigonal-bipyramidal geometry.
