Coordination Polymers of γ,γ'-Dipyridyl and Mononuclear Benzoates M(OOCPh)2[O(H)Me]4 (M = Ni, Co)

Аннотация

The slow diffusion of a γ,γ′-dipyridyl adduct solution in methanol into a methanol solution of the adduct M[(OOCPh]₂[O(H)Me]₄ (1) at the reagent ratio 1 : 1 and room temperature was found to result in the 1D coordination polymers {dipyM(OOCPh)₂[O(H)Me]₂}_n (M = Ni (2), green; Co (3), orange) and {(dipy)₂Co₂(µ-OOCPh)₂(η²-OOCPh)₂ ⋅ MeOH}_n (4), pink). Orange polymer 3 was the only product when the initial reagents were diluted three times, and their diffusion was performed at 5°C. Synthesized polymers 2–4 were studied by chemical and X-ray diffraction analyses and IR spectroscopy.
