چکیده انگلیسی
The new didentate ligand diethyl pyridin-3-ylmethyl phosphonate (3-pmpe) and three of its Zn(II) complexes are described. IR and X-ray analyses show that in the reaction of ZnCl2 with 3-pmpe in methanol three crystalline polymorphs are formed: [Zn(3-pmpe)Cl2]2 (1) and [Zn(3-pmpe)Cl2]n (2 and 3). In these crystals 3-pmpe acts as a didentate N,O-bridging ligand and Zn(II) is in a slightly distorted tetrahedral ZnNOCl2 environment. Zn2+ ions in 1 are doubly bridged by the 3-pmpe ligand, resulting in the formation of dinuclear species. In polymeric compounds 2 and 3 Zn2+ ions are singly bridged by the 3-pmpe, resulting in the formation of one-dimensional chains.
