A novel two-dimensional lead(II) coordination polymer 1, [C11H7Cl2NO3Pb]n, has been prepared by solvothermal reaction of new bridging ligand(5-chloro-quinolin-8-yloxy)acetic acid(HL) with PbCl2, and its structure was characterized by IR, elemental analysis, TG-DTA and single-crystal X-ray diffraction analysis. The crystal is of monoclinic system, space group P21/c with a = 16.7603(7), b = 8.6907(4), c = 8.4745(3), β = 101.1110(11)°, C11H7Cl2NO3 Pb, Mr = 479.27, V = 1211.25(9)3, Z = 4, Dc = 2.628 g/cm3, F(000) = 880, μ = 14.367 mm-1, R = 0.0173 and wR = 0.0508. The asymmetric unit contains one lead(II) cation, one(5-chloro-quinolin-8-yloxy)acetate(L) ligand and a chloride ion. The PbII center is hepta-coordinated in a distorted pentagonal bipyramidal geometry. The coordination sphere of the Pb atom is completed by two oxygen atoms and one nitrogen atom of the same L ligand, two bridging chloride ions and two bridging oxygen atoms of two adjacent L ligands. Two PbII centers are linked by the two L ligands to form a C2-symmetric dimer unit with a planar [Pb2O2] ring. Each dimer unit acts as a secondary building unit(SBU) and links adjacent four dimer units by the chloride atoms and oxygen atoms of carboxylate groups of L, forming a two-dimensional array. Such two-dimensional layers are packed through intermolecular C–H···Cl hydrogen bonds into a three-dimensional supramolecular structure. When the dimer unit is viewed as a 4-connected node, 1 is simplified as a 4-nodal 2-D network with square lattices of the diagonal lengths to be 6.079(1). The fluorescence emission peak of complex 1 appears near 407 nm.

Synthesis and Structural Characterization of a Tetranuclear Copper Complex with 2-Amino-1,3-thiazole

The title tetranuclear complex,(μ4-oxo)-hexakis(μ2-chloro)-tetrakis(2-amino-1,3-thiazole-N)-tetra-copper(ii) [Cu4(μ4-O)(μ-Cl)6L4](1,L=2-amino-1,3-thiazole) was synthesized by the reaction of CuCl2·2H2O with 2-amino-1,3-thiazole in methanol and characterized by IR spectra and X-ray diffraction.Complex 1 crystallizes in triclinic,space group P1 with a=9.7137(2),b=10.7005(2),c=14.6505(2),α=83.9550(10),β=82.0930(10),γ=67.1640(10)°,V=1387.84(4)3,Mr=883.43,Z=2,μ=3.927 mm-1,Dc=2.1144 g/cm3,F(000)=868,R=0.0332 and wR=0.0814.The complex contains a tetrahedron of four CuII atoms coordinating to a central μ4-O atom,with the six edges of the tetrahedron bridged by six Cl atoms.The Cu-O bond distances range from 1.910(2) to 1.918(2),Cu-Cl from 2.3501(11) to 2.5924(10),and Cu-Cu from 3.1003(6) to 3.1663(6).The coordination geometries of the four coppers distort from trigonal bipramid to tetragonal pyramid with different distortion factors.The free animo groups of the ligands result in a lot of N-H···Cl and N-H···N intra-and intermolecular hydrogen bonds.
