Abstract
The coordination chemistry of the organozinc-nitrogen compounds EtZnNPh2 and EtZnNPhCOZ (Z=H, Me, OMe, SMe and NPh2) has been studied. Whereas EtZnNPh2 is dimeric [as in Zn(NPh2)2], with three-coordinate zinc, replacement of a Ph group in EtZnNPh2 by COZ leads to higher association and four-coordination of zinc. Such compounds are trimeric
