A microporous [Ni3(μ3-OH)] cluster-based framework with 9-connected ncb topology

Abstract: A porous metal organic framework [NiIIINiII 2(μ 3-OH)(bdc)1.5(int)3] n x(solvents) (1: bdc=1,4-benzenedicarboxylate; int=isonicotinate) based on the trinuclear Ni3(μ 3-OH) units was solvothermally synthesized and structurally characterized. It features a three-dimensional 9-connected ncb-type framework with two kinds of cage substructures and large one-dimensional channels. Both N2 and CO2 gas sorption studies of 1 were investigated to demonstrate the permanent porosity in 1. [Copyright &y& Elsevier]
