Synthesis and Structure of Bis—（o—vanillin）di—pyridine Nickel（Ⅱ）—pyr

摘要

cqvip:The structure of the complex bis (o vanillin) di pyridine nickel(Ⅱ) ([Ni(C 8H 7O 3) 2(C 5H 5N) 2]·2H 2O·C 5H 5N, M r =634.31) has been synthesized and determined by X ray analysis. The crystal data are as follows: Monoclinic, P2 1/n, a=12.273(1), b=17.470(1), c=14.731(1), β=98.45(1)°, V=3125.8(3) 3, Z=4, D c =1.34mg·m -3 , μ= 0^674mm -1 , F (000)=1328, final R=0.0428, R w =0.1228 for 4528 observable reflections with I≥2σ(I ). The Nickel(Ⅱ) atom in the complex has a slightly distorted octahedral coordination geometry and is six coordinated by four O atoms from two O Vanillin ligands and two N atoms from two pyridines. In the crystal, the Ni(Ⅱ) complex and water molecules are linked through a network of hydrogen bonds.
