A new nano-sized lead(II) coordination polymer, [Pb(2-bpdh)(NO3)2]n (1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4-hexadiene)}, was synthesized by a sonochemical method. The structure of 1 may be considered coordination polymer of lead(II) consist of metallocyclicchains formed by bridging NO3- and 2-bpdh l...

Six new 1-benzoyl-3-phenylthiourea and 1-benzoyl-3-(2-methylphenyl)thiourea complexes of mercury(II) were obtained in the reactions of the ligands with HgX2 in methanol (X = Cl, Br, I). Their structures, determined by single-crystal X-ray diffraction analysis, exhibit different stoichiometries and molecular organization. Coordination centers adopt more or less distorted tetrahedral geometry (fi...

A new zinc compound, together with a corresponding series of Zn-4f heterometallic coordination polymers, namely, [Zn(H2PBDA)(PBDA)]n (1), {[Ln2(PBDA)2·2H2O] [Zn2(PBDA)2Cl2]}n [H2PBDA = 3-(pyridin-3-yl-oxy) benzene-1,2-dicarboxylic acid, and Ln = Pr(2), Nd(3), Eu(4), Gd(5), Dy(6), Ho(7), Er(8)] have been hydrothermally synthesized and characterized systematically. Polymers 2-8 feature two-dimens...

Abstract A novel coordination polymer, [Pb(L)(1,3-bdc)]·2H 2 O ( 1 ), (L = 2-(2,6-dichlorophenyl)-1 H -imidazo[4,5- f ][1,10]phenanthroline, 1,3-H bdc 1,3-benzenedicarboxylic acid) has been successfully prepared under hydrothermal conditions. The structure of is a 1D chain structure, which further stacks together to form 3D supramolecular architecture by π–π interactions and C–H⋯π interactions....

In order to investigate the coordination chemistry of O-alkyl N-aryl thiocarbamate ligands toward coinage metals, CuBr was reacted with one equivalent MeOC(=S)N(H)Ph L in MeCN solution afford 1D-polymeric title compound [{Cu(μ2-Br)2Cu}{μ2-MeOC(=S)N(H)Ph}2]n CP1. Compound 1 characterized by IR spectroscopy and an elemental analysis. The formation a polymeric 1D ribbon built upon μ2-bridging brom...

One Co(ii) SCO coordination polymer [Co(enbzpy)(μ1,5-dca)]n(PF6)n (·PF6) has been isolated and characterised structurally and magnetostructurally. The properties of ·PF6 are compared with the reported perchlorate analogue [Co(enbzpy)(μ1,5-dca)]n(ClO4)n (·ClO4). The gradual spin transition in ·PF6 in contrast to an abrupt spin transition with a hysteresis loop in ·ClO4 has been analysed in terms...
