Synthesis and crystal structure of copper II and silver I complex with 1,4-diazabicyclo[2.2.2]octane[Cu(CBC)2(Dabco)(H2O)] n (1) and [Ag2(HBC)2(Dabco)] n (2)

Two 1D polymeric complex, [Cu(CBC)(2)(Dabco)(H2O)] (n) (1) and [Ag-2(HBC)(2)(Dabco)] (n) (2) have been synthesized and characterized by X-ray single crystal analysis, where CBCH is p-chlorobenzoic acid, HBCH 2 is 2-hydroxybenzoic acid and Dabco is 1,4-diazabicyclo[2.2.2]octane. Complex 1 has been obtained in high yield by hydrothermal synthesis from CuO and CBCH and Dabco, and complex 2 has been obtain by evaporation of the solvent from silver salicylate and Dabco, 1 crystallizes in the orthorhombic space group Pmn2 (1) with a = 24.3310(5) angstrom, b = 6.9050(6) angstrom, c = 5.9980(5) angstrom, Z = 2, V = 1007.70(4) angstrom(3) and Dx = 1.657 g cm(-3), 2 crystallizes in the monoclinic space group P2 (1) /m with a = 10.292(3) angstrom, b = 6.913(2) angstrom, c = 14.417(4) angstrom, beta= 95.660(5), Z = 2, V = 1020.8(5) angstrom(3) and Dx = 1.959 g cm(-3). The final R value is 0.0302 for 1323 measured reflections for 1 and the final R value is 0.0684 for 1545 measured reflections for 2. The atomic arrangement is built by infinite one-dimensional polymeric chain in both complexes. These chains are cross-linked by hydrogen bonds involving the coordinated water molecules to form a two-dimensional framework in complex 1.
