Using the single crystal X-ray diffraction data (150 K, Bruker X8 Apex CCD autodiffractometer, MoK alpha radiation), the crystal structure of the [Cd2L2Cl4]center dot CH2Cl2 (L = pyrazolylquinoline, the derivative of monoterpenoid (+)-3-carene) compound is determined. Crystals are monoclinic, unit cell parameters are: a = 10.7005(4) angstrom, b = 16.8491(4) angstrom, c = 11.9658(4) angstrom, beta = 93.308(1)degrees, P2(1) space group. The structure is formed from discrete acentric molecules of a binuclear [Cd2L2Cl4] complex and uncoordinated CH2Cl2 molecules. The Cd2+ ions coordinate N atoms of bidentate chelating ligands L, which leads to the closure of two five-membered chelate CdN3C rings. The coordination sphere of Cd atoms also includes three Cl atoms (two bridging and one terminal), consequently, two CdCl3N2 coordination sites and a Cd2Cl2 metal ring are formed. The Cl3N2 polyhedra have the form of distorted tetragonal pyramids. The CH2Cl2 molecules located in the channels formed by the complexes are linked with them by weak H-bonds. The excitation spectra of L and the CdLCl2 compound contain bands with lambda(max) of 352 nm and 360 nm respectively. At 300 K and lambda(excit) 350 nm, in the photoluminescence spectrum of L a rather intense broad split band with lambda(max) 372 nm and 386 nm is observed. The photoluminescence spectrum of the CdLCl2 compound contains a broad band with lambda(max) 418 nm. The photoluminescence intensity of this compound is significantly lower than that of L.
