Abstract

[Co(bmib)(bpda)]·H2O (1) and [Ni(bmib)(bpda)] (2) (H2bpda = biphenyl-3,4′-dicarboxylic acid; bmib = 4,4′-bis(2-methylimidazol-1-ylmethyl)benzene) were synthesized under hydrothermal conditions. The structures have been determined by single-crystal X-ray diffraction analyzes and further characterized by elemental analyzes, IR, PXRD, and TGA. Compounds 1 and 2 possess a threefold interpenetrated (65.8) architecture that incorporates left- and right-handed helical chains. The difference of angles between the coordination spacers in 1 and 2 causes a large difference along the c-axis.
