摘要
The two title compounds [Cu（sdba）（py）2（H2O）]n·2n（py） 1 and [Cu（sdba）（phen）（H2O）]n 2 （H2sdba = 4,4′-sulfonyldibenzoic acid, py = pyridine, phen = 1,10-phenanthroline） have been synthesized and characterized by single-crystal structure determination, IR and TG analyses. Compound 1 crystallizes in orthorhombic, space group Pbcm with a = 5.9833（12）, b = 22.333（5）, c = 24.571（5）A, V = 3283.3（12） A^3, Z = 4, C34H30N4OTSCu, Mr = 702.22, Dc = 1.388 g/cm^3, F（000） = 1396,μ（MoKa） = 0.780 mm^-1, the final R = 0.0599 and wR = 0.1767 for 3416 observed reflections with I 〉 2σ（I）. Compound 2 crystallizes in monoclinic, space group C2/c with a = 22.9549（4）, b = 12.2443（3）, c = 17.8687（4）A, β = 110.873（1）°, V = 4692.69（18）A^3, Z = 8, C26H18N2O7SCu, Mr = 566.02, Dc = 1.602 g/cm^3, F（000） = 2312,μ（MoKa） = 1.078 mm^-1, the final R =0.0697 and wR = 0.1330 for 3452 observed reflections with I 〉 2σ（I）. In both structures, the Cu^Ⅱ metal centers adopt five-coordination in slightly distorted tetragonal pyramidal geometries, while the second N-donor ligands bond or chelate to Cun ions as the terminal moiety. The weak interactions extend the two structures into high-dimensional supramolecular coordination-polymers.
