摘要
The title compound,C10H56Cl10Cu4N4O5,Mr=1041.40,has been prepared by reaction of CuCl and choline chloride in CH3CN.It crystallizes in the monoclinic system,space group C2/c with a= 22.55 (1),b=10.442(2),c=18.742(3),β=113.40(3)°,V=4050(3)3,Z=4,λ(MoKα)=0.71069,F(000)=2120,Dc=1.71 g/cm3 and μ(MoKα)=27.81 cm-1.The structure was solved by direct methods and refined by full-matrix least squares to final R and Rω values:0.070 and 0.076,respectively.The tetranuclear anion contains a central oxide ion coordinated tetrahedrally to four copper(Ⅱ) ions;the copper(Ⅱ) ions are bridged in pairs by six chloride ions.The remaining four chloride ions completed a trigonal-bipyramidal coordination sphere around each copper(Ⅱ) ion.There are two crystallographically independent and virtually identical cations in each asymmetrical unit.
