The optically active complex [(ZnLCl2)-Cl-1] (I), where L-1 = pyrazolylquinoline (a derivative of monoterpenoid (+)-3-carene) is obtained. Single crystals of compound I are grown and its crystal structure is determined from X-ray diffraction data (X8 APEX diffractometer, MoK (alpha) radiation, 3031 F (hkl)). The crystals of I are monoclinic; unit cell dimensions are: a = 8.4189(10) , b = 12.7194(11) , c = 9.7652(12) , beta = 111.318(3)A degrees, V = 974.14(19) (3), Z = 2, d (x) = 1.499 g/cm(3), space group P2(1). Complex I is composed of discrete mononuclear molecules. In coordination of Cl atoms and two N atoms of the bidentate cycling ligand L-1, a distorted tetrahedral Cl2N2 polyhedron forms at Zn. In the complex molecule, a fragment consisting of five-membered pyrazole and chelate rings, a five-membered carbocycle, and also two six-membered quinoline rings is almost planar. Solid complex I shows strong white photoluminescence at 300 K and lambda(exc) = 365 nm in the 400-700 nm range with lambda(max) = 490 nm.
