The structure indicates that the complex crystallizes in monoclinic,space group P21/c with a=1.273 4(3) nm,b=1.237 5(3) nm,c=2.403 2(5) nm,β=90.51(3)°. V=3.786 6(13) nm3,Z=2,Dc=1.429 Mg.m-3,μ=1.445 mm-1,F(000)=1 660,and final R1=0.055 5,wR2=0.129 7. The crystal structure shows that the dinuclear Cu2N6 unit is almost planar in which each Cu(Ⅱ)ion was five-coordinated by one nitrogen atoms from MMBPT and two chlorine in the basal positions and two nitrogen atoms from two MMBPTs respectively in the axial one,to form a distorted trigonal bipyramidal geometry. Magnetic measurements reveal a relatively strong antiferromagentic interaction in the complex. CCDC:720011.展开更多
