چکیده
The title compound, [Hg5Br10(C7H8N2O)2] n , contains two μ3-bridging Br atoms, six μ2-bridging Br atoms and two terminal Br atoms. One Hg(II) atom, lying on an inversion center, adopts a distorted octa-hedral geometry defined by six Br atoms. Two Hg(II) atoms adopt a distorted square-pyramidal geometry by five Br atoms and the other two Hg(II) atoms have a distorted tetra-hedral geometry by two N atoms from a chelating O-methyl pyridine-2-carboximidate ligand and two Br atoms. The Br atoms link the Hg(II) atoms into a ribbon structure along [100].

In the title coordination polymer, {[CdBr2(C5H9NO2)]·H2O} n , the Cd(II) ion is coordinated by four bromido ligands and two carboxyl-ate oxygen atoms of two symmetry-related proline ligands, which exist in a zwitterionic form, in a distorted octa-hedral geometry. There is an intra-molecular N-H⋯O hydrogen bond between the amino group and the carboxyl-ate fragment. Each coordinating ligand bridg...

In the title polymeric complex, [HgBr(2)(C(10)H(14)N(2))](n), each nicotine mol-ecule is bonded to two adjacent Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming zigzag chains along [010]. The coordination around mercury is completed by two bromido ligands resulting in a distorted tetra-hedral arrangement.

In the title compound, [PbBr(2)(C(14)H(12)N(2))](n), the Pb(II) atom lies on a twofold rotation axis. The N-heterocycle-chelated Pb(II) atom exists in a distorted octa-hedral geometry owing to two long Pb⋯Br inter-actions [2.9562 (5) and 3.2594 (5) Å]. These result in a zigzag chain running along the c axis. The lone pair is stereochemically inactive.

In the title complex, {[Cu(SiF(6))(C(11)H(8)N(2)O)(2)]·2H(2)O}(n), the Cu(II) atom adopts an N(4)F(2)-octa-hedral coordination geometry with four pyridine N atoms in the equatorial sites and two F atoms in the axial sites. The di-3-pyridyl-methanone and hexa-fluoro-silicate ligands act as bidentate ligands, linking symmetry-related Cu(II) atoms. Water mol-ecules form O-H⋯O and O-H⋯F hydrogen bo...

A new thulium(III)-copper(I) heterometallic coordination polymer, [Cu(4)Tm(2)Br(3)(C(6)H(4)NO(2))(6)(OH)(H(2)O)(4)](n), has been prepared by a hydro-thermal method. The Tm and both Cu atoms lie on mirror planes. The Tm atom is seven-coordinate with a capped distorted trigonal-prismatic coordination geometry, while the Cu atoms adopt trigonal CuBrN(2) and tetra-hedral CuBr(3)N coordination modes...
