Synthesis, separation, and assignment of the seven geometric isomers of [Co(dien)(ibn)Cl]2+.
All seven possible geometric isomers (four mer and three facial) for the [Co(dien)(ibn)Cl](2+) system have been synthesized (dien = diethylenetriamine, ibn = 1,2-diamino-2-methylpropane). Their structures in dimethyl sulfoxide solution have been uniquely determined by two-dimensional NMR spectroscopy (DQCOSY and NOESY).
