摘要
Three novel coordination polymers, {[Co(L)(SO4)(H2O)](CH3OH)}(infinity) (1), {[Cd(L)(2)(SiF6)](H2O)}(infinity) (2) and [Zn(L)(NO3)(2)](infinity) (3), synthesized from 1,4-di(benzimidazole-1-yl)benzene (L), have been characterized by infrared spectroscopy, elemental analysis and single crystal X-ray diffraction. Compounds 1-3 exhibit different structures. Complex 1 has a 3-D diamond network containing 1-D Co-II chains connected by SO42- anions; 2 has a 3-D alpha-Po framework with 1-D porous channels along the c axis; and 3 has a 1-D zig-zag chain structure with a 2-D supramolecular network based on pi-pi interactions. The magnetic properties of 1 and the solid state fluorescence spectra of 2 and 3 have also been explored.
