Abstract
Two 3D supramolecular architectures, [Cu(tmbdc)(NH3)2] n , 1, (tmbdc = 2,3,5,6-tetramethylbenzenedicarboxylate), and {[Cu3(btc)2(NH3)6(H2O)]·2H2O} n , 2, (btc = 1,3,5-benzenetricarboxylate) have been assembled with 1D or 2D coordination polymers as supramolecular synthons. The geometry matching of the moieties is the key factor for the formation of the two supramolecular architectures by the cooperation of coordination bonds, hydrogen bonds and π···π interactions. Crystal data for 1: Formula CuC12H18N2O4, monoclinic, space group P21/c, a = 9.0134(5), b = 10.8785(5), c = 6.4702(3) Å, β = 91.679(1)°, V = 634.15(5) Å3, Z = 2, R 1 = 0.0251 and wR 2 = 0.0722. Crystal data for 2: Formula Cu3C18H30N6O15, monoclinic, space group C2/c, a = 13.9213(5), b = 17.1210(6), c = 12.5271(5) Å, β = 114.779(1)°, V = 2710.89(17) Å3, Z = 4, R 1 = 0.0245 and wR 2 = 0.0665. The positions and isotropic displacement parameters of all the hydrogen atoms are refined.

The geometry matching of the moieties of 1D or 2D coordination polymers leads to the formation of two 3D supramolecular architectures by the cooperation of coordination bonds, hydrogen bonds and π⋯π interactions.
