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

A porous metal organic framework [NiIIINiII2(μ3-OH)(bdc)1.5(int)3]n x(solvents) (1: bdc = 1,4-benzenedicarboxylate; int = isonicotinate) based on the trinuclear Ni3(μ3-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.
