Co-crystallization of pztcH_4 with 4,4?-bipyridine(4,4?-bipy) in pH = 3~4 and 1~2 gave two new binary molecular adducts: [(4,4?-bipy H2)(pztc H_2)](1) and [(4,4?-bipy H_2)(pztcH_3)(Cl)]·4H_2O(2), respectively. Compounds 1 and 2 have been characterized by IR, elemental analysis, NMR and X-ray single-crystal diffraction. Compound 1 crystallizes in triclinic, space group P1 with a = 5.7752(12), b = 7.9126(16), c = 9.4492(19) ?, α = 97.49(3), β = 107.71(3), γ = 94.52(3)o, V = 404.62(14) ?3, Z = 1, μ = 0.137 mm-1, Dc = 1.692 Mg/m3, C_(18)H_(12)N_4O_8, Mr = 412.32, F(000) = 212, S = 1.025, R = 0.0360 and w R = 0.0973. Compound 2 crystallizes in monoclinic, space group C2/c with a = 17.093(3), b = 7.7665(16), c = 18.414(4) ?, β = 113.36(3)o, V = 2244.1(8) ?3, Z = 4, μ = 0.244 mm-1, Dc = 1.542 Mg/m~3, C_(18)H_(21)ClN_4O_(12), Mr = 520.84, F(000) = 1080, S = 1.021, R = 0.0343 and w R = 0.0978. In compound 1, pztc H22- anions self-formed 2-D sheets by strong Oacid-H···Oacidhydrogen bonds, which are further extended to form a 3-D supramolecular network bridged with 4,4?-bipy via N-H···Oacid interactions. In compound 2, besides the 1-D chain constructed by pztc H3-itself through strong H-bond Oacid-H···Oacid, the other chain is constructed with 4,4?-bipy H22+, Cl-anion and water molecules by moderate H-bonds and Ow-H···Cl and N-H···Ow. The two chains are linked with μ3-connected water molecules resulting from the combination of strong synthon-assisted H-bonding O_(acid)-H···O_w to afford an interlaced 3-D network.
Co-crystallization of pztcH_4 with 4,4? -bipyridine (4,4? -bipy) in pH = 3-4 and 1-2 gave two new binary molecular adducts: [(4,4? -bipy H2) (pztc H2 (1) and [(4,4? -bipy H_2) (pztcH_3) (Cl)] · 4H_2O (2), respectively.
