Synthesis and Crystal Structure of a Mixed Complex[ Cu(1, 10-phen)(CH2(COO)2)(H2O)]2·3H2O |

Abstract: | Blue block crystals of Cu( 1,10 - phen) ( CH2 ( COO)2 ) (H2O) ]2· 3H2O were obtained at room temperature over a period from the filtrate which was resulted from the addition of a alcohol solution of 1,10- philolin into the filtered resultant of the reaction of basic cupric carbonate with aqueous propanioic acid.Single - crystal X - ray diffraction analysis indicates that it crystallizes in a triclinic system with space group P1(No.2), α = 11.560(2),b = 11.750(2),c = 12.510(3) A,α =92.13(3)°,β= 105.50(3)°,γ=109.30(3)°, v = 1530.6(5)A3, z = 2, Mr = 781.66, F(000) = 800, Dc = 1. 696 g/cm3, μ(MoKα) =1.467 mm-1, R = 0.0392, and wR2= 0.0967 for 4560 reflections with I > 2.0σ(I). Each Cu atom is coordinated in a distorted square - pyramid geometry by two N atons of 1,10 - philolin, and two O atoms from two carboxyl group of propanioic acid, and one O atom from a coordination water molecule occupying the apical position with a long Cu - O distance. A dimer Cu(1,10- phen) (CH2(COO)2) (H2O) ]2 is formed by the inter- molecular hydrogen bonding. The crystal structure is formed by the interconnection of the dimers and crystal water molecules via hydrogen bonding. |
