Synthesis and Supramolecular Structure of Chloro（1,10-phenanthroline ）copper（I） Hexahydrate

1INTRODUCTION Atom transfer radical addition is an efficient me-thod for carbon-carbon bond formation in organic synthesis[1,2].In some of these reactions,a transi-tion-metal catalyst acts as a carrier of the halogen atom in a reversible redox process.The transition-metal-catalyzed has been successfully used to con-trol radical polymerization[3].In the process,the transition-metal species initially abstracts halogen atom X from organic halide to form oxidized species and carbon-centered r…

Synthesis and Supramolecular Structure of Chloro(1,10-phenanthroline)copper(I) Hexahydrate

The title compound, C24H28ClCuN4O6 (Mr = 567.49), has been prepared and its crystal structure has been determined by X-ray diffraction method. The crystal belongs to mono- clinic, space group C2/c with a = 23.1905(14), b = 30.1877(12), c = 7.4881(3)(A), β = 97.631(2)o, V = 5195.8(4) (A)3, Z = 8, Dc = 1.451 g/cm3,μ = 0.989 mm-1, F(000) = 2352, S = 1.030, R = 0.0694, wR = 0.2120 (I > 2σ(I)), R = 0.0950 and wR = 0.2322 (all data). The crystal consists of the Cu(I) complex and lattice water molecules. The Cu(I) atom is coordinated by two phenanthroline (phen) molecules and one chlorine anion with a distorted trigonal dipyramidal coordination geometry. By the aid of aromatic π-πstacking, the Cu(I) complex molecules form two-dimensional supramo- lecular layers. Lattice water molecules locate between the adjacent layers to form a three-dimen- sional sandwich-like supramolecular structure.
