Abstract

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.
