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)°.

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.
