It is a co-crystal consisting of two different neutral zinc(H) complexes with Hbpbm (Hbpbm = 4- bromo-2-(benzimidazol-2-yl)phenol) and Hnpbm (Hnpbm = 2-(1-butylbenzimidazol-2-yl)phenol). One is a monomeric mixed-ligand complex of [Zn(bpbm)(npbm)] 1 and the other a dimer of [Zn2(npbm)4] 2 with their ratio of 2:1. Thus the overall formula for the title compound is 21.2. Adjacent 1 and 2 are connected to each other by intermolecular hydrogen bonding interactions in the lattice. The crystal data: monoclinic, space group P21/c, a = 15.0141(12), b = 20.9941(17), c = 18.4686(15) A, β = 97.445(2)°, V = 5772.4(8) A^3, Mr= 2429.68, Z = 2, Dc = 1.398 g/cm^3,μ = 1.579 -1 mm , F(000) = 2504, R = 0.0637 and wR = 0.1771 for 6464 observed reflections (I 〉 2σ(I)).

A novel two-dimensional Mn(II) coordination polymer, [Mn3(L)R(cis-chdc)fftrans- chdc)]n (L = 2-amino-4-(1H-imidazo[4,5-J][1,10]phenanthrolin-2-yl)phenol and chdc = 1,4-cyclo- hexanedicarboxylate), has been ...A novel two-dimensional Mn(II) coordination polymer, [Mn3(L)R(cis-chdc)fftrans- chdc)]n (L = 2-amino-4-(1H-imidazo[4,5-J][1,10]phenanthrolin-2-yl)phenol and chdc = 1,4-cyclo- hexanedicarboxylate), has been hydrothermally synthesized and characterized by elemental analysis, IR, TG PL and single-crystal X-ray diffraction. Crystallographic data for this compound: monoclinic space group P2/n with a = 11.0058(13), b = 9.0179(11), c = 28.431(3) A, β = 92.850(2)°, V = 2818.3(6) A3, Z = 2, C62Hs6Mn3N10O14, Mr = 1329.99, Dc = 1.567 g/cm3, F(000) = 1370, p(MoKa) = 0.742 mm-1, R = 0.0553 and wR = 0.1421. The chdc carboxylates bridge the Mn(II) atoms to form a trinuclear Mn(lI) cluster. The cis-chdc ligands are held together by the trinuclear Mn(II) clusters to result in a chain structure. Further, the trans-chdc ligands link adjacent chains to furnish a two-dimensional network. The π-π interactions between neighboring layers link the adjacent layers into a three-dimensional supramolecular architecture. Moreover, the N-H...O and O-H...O hydrogen bonds further stabilize the 3D supramolecular architecture.展开更多
