Synthesis and Crystal Structure of an Anionic Linear Trinuclear Copper(Ⅱ) Complex Containing 2-Thenoyltrifluoroacetonato and Acetato Ligands
A novel anionic trinuclear linear copper(Ⅱ) complex {[Et3NH][Cu1.5(CH3COO)-(TTA)3]}2(1,TTA = 2-thenoyltrifluoroacetonate) has been synthesized in a direct reaction involving copper(Ⅱ) acetate monohydrate,TTA and excess triethylamine base in dichloromethane solvent.Green colored X-ray quality crystals of 1 were grown from n-hexane solvent at room temperature.The data were collected at 100 K.Compound 1 crystallizes in the monoclinic P21/n space group(a = 11.2141(8),b = 19.0965(13),c = 17.3680(14) ,β = 90.225(2)°,V = 3719.3(5) 3,Mr = 1840.14,Dc = 1.643 Mg/m3,F(000) = 1866,μ = 1.129 mm-1 and Z = 2).The asymmetric unit of 1 contains two copper atoms,one of which lies on a crystallographic inversion center with 50% occupancy.
