摘要

Two 3Dsupramolecular architectures, [Cu(tmbdc) (NH3)_2] _n, 1, (tmbdc = 2,3,5,6-tetramethylbenzenedicarboxylate), and {[Cu_3(btc)_2(NH_3)_6(H _2O)]._2H_2O}_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 CuC_(12)H_(18)N _2O_4, monoclinic, space group P2_(1/c), a = 9.0134(5), b = 10.8785(5), c = 6.4702(3) ?, β = 91.679 (1)°, V = 634.15(5) ? 3, Z = 2, R_1 = 0.0251 and w_(R2) = 0.0722. Crystal data for 2: Formula Cu_3C_(18)H_(30)N _6O_(15), monoclinic, space group C2/c, a = 13.9213(5), b = 17.1210(6), c = 12.5271(5) ?, β = 114.779(1)°, V = 2710.89(17) ? 3, Z = 4, R_1 = 0.0245 and w_(R2) = 0.0665. The positions and isotropic displacement parameters of all the hydrogen atoms are refined.
