Abstract
Two transition-metal coordination polymers {[Zn2(L)2(HCOO)2]}n (I) and {[Cd2(L)3(HCOO)] ∙ 2H2O}n(II) (L = 1,3-bis(4-(methoxycarbonyl)benzyl)-1H-imidazol-3-ium anion) have been synthesized via solvo-thermal method. Both of the coordination polymers I and II were characterized by single-crystal X-ray diffraction (CIF files CCDC nos. 1834629 (I) and 1834630 (II)), FT-IR spectroscopy, elemental analysis and thermogravimetric analysis. The results shown compound I is a two dimensional sql layer structure containing interlocking structure between the left and right helix chains, and compound II is rare three dimensional six-fold interpenetrating dia topology framework. Luminescence investigations revealed that both of compound I and II emitted blue light.
