Abstract

In this extensive study, four coordination polymers, [Cu(mu (4)-dmg)(mu-pbix)(0.5)](n) (1), {[Cu(mu-dmg)(mu-pbix)] center dot 2H(2)O}(n) (2), {[Zn-2(mu-dmg)(mu-SO4)(mu-pbix)(2)] center dot H2O}(n) (3) and {[Cd(mu-dmg)(H2O)(mu-pbix)] center dot H2O}(n) (4) were synthesized with hydrothermal methods by using 3,3-dimethylglutarate (dmg) and 1,4-bis(imidazol-1ylmethyl)benzene (pbix). The complexes were characterized by elemental analyses, IR spectroscopy and single crystal X-ray diffraction techniques. Single crystal X-ray results demonstrated that complex 1 displayed a 2D network. In the synthesis of 2, Cu(CH3COO)(2) center dot H2O was used instead of Cu(NO3)(2) center dot 3H(2)O and a structurally different complex 2 was obtained with a 2-fold interpenetrated 3D framework (cds topology). Complexes 3 and 4 were interpenetrated with each other to form 3D+3D -> 3D frameworks with bbe-3,4-Cmmm and cds topologies, respectively. The dmg ligand exhibited a new coordination mode, mu-eta(1):eta(1):eta(0):eta(1). Thermal behaviors, photoluminescence and topological properties of the complexes were also investigated.
