The complex of CdCl2 with 2-(3,5-dimethylpyrazol-1-yl)-4-methylquinoline (L), Cd-2(L)Cl-4(I), is synthesized. According to the X-ray diffraction data, the structure of coordination polymer I is formed by chains in which two crystallographically independent Cd atoms linked by the bridging Cl atoms have different coordination numbers (5 and 6) and different environments. Five Cl atoms form the coordination polyhedron of the Cd(2) atom: a square pyramid (Cd-Cl 2.554(3)-2.689(3) angstrom) completed to a bipyramid by the Cl atom at a substantially longer distance of 2.865(4) angstrom. Two Cl atoms and the N atom of quinoline fragment L are arranged in the equatorial plane of the coordination polyhedron of the Cd(1) atom, which is a distorted trigonal bipyramid. The axial vertices are occupied by the N atom of the pyrazole cycle of L and the Cl atom. Five-membered metallocycles CdCN3 are formed upon the coordination of bidentate chelating ligands L. The planes of L of two adjacent chains are parallel (the distances between them are similar to 3.5 angstrom), which suggests the pi-pi interaction between the planes. The luminescence excitation spectrum of compound I has a broad band with lambda(max) = 350 nm. The spectrum of bright blue photoluminescence of compound I (300 K, lambda(exc) = 340 nm) contains an intense band with lambda(max) = 420 nm.
