The syntheses and crystal structures of a three-dimensional (3D) coordination network [Zn4(2-mBIM)5- (C2H 6NCOO)(HCOO)(μ-OH)]·DMF (1·DMF; 2-mBIM = 2-methylbenzimidazolate) and a two-dimensional (2D) layer [Zn 2(2-mBIM)3(HCOO)(H2O)]·DMF (2·DMF) are reported. Different structures were produced depending on the ratio of reactants. Structurally, 1 illustrates the formation of a unique framework based on a 2-mBIM bridge with the side group on an imidazole ring, while 2 possesses a honeycomb layer built up purely from imidazolates. For gas sorption, CO2 is adsorbed on the activated phase of 1 but N 2 is not taken up.
