Zinc salts of low or zero water content were obtained from isolated and identified by crystal structure determinations. All contain octahedral zinc to which 2, 3, 4, 5, or 6 aldehyde the hexahydrates of zinc nitrate, zinc perchlorate, and zinc tetrafluoroborate by dehydration with triethoxymethane o
Both 1 : 1 and 1 : 2 complexes are formed by zinc(II) halides and triarylphosphines unless electronic and/or steric factors intervene. Tri-p-chlorophosphine (a weaker base than PPh 3 ) forms only a 1 : 1 complex, whereas bulky tri-(ortho-substituted phenyl)phosphines do not react. The complexes ZnX
