چکیده
In the title Pb(II) complex, [Pb(2)(C(2)Cl(3)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)](n), the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one Pb(II) ion and simultaneously bridges a neighbouring Pb(II) ion via the third O atom, and the trichloro-acetate anion is bidentate, bridging two Pb(II) ions. The coordination geometry is based on a penta-gonal-bipramidal geometry defined by an N(2)O(5) donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The coordination polymer has a zigzag topology along [010] and comprises alternating eight-membered {PbONO}(2) and {PbOCO}(2) rings.

The title compound, [Pb(2)(C(7)H(5)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], crystallizes as a dinuclear centrosymmetric dimer containing two Pb(II) atoms bridged by two benzoate ligands. Each Pb(II) atom is seven-coordinated by a water mol-ecule, a nitrate anion, a 1,10-phenanthroline (phen) ligand and two benzoate anions. The crystal packing is stabilized by O-H⋯O hydrogen bonds and by...

In the centrosymmetric dinuclear title compound, [Pb(2)(C(7)H(5)O(2))(4)(C(12)H(8)N(2))(2)], two Pb(2+) ions are connected by two tridentate bridging benzoate anions. The Pb(2+) ion is seven-coordinated by five O atoms from three benzoate anions and two N atoms from the 1,10-phenanthroline ligands. The benzoate anions adopt two different coordination modes, one bidentate-chelating and one tride...

The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand...

The title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(8)N(2))(2)], consists of dimeric units built up around a crystallographic symmetry centre. Each cadmium(II) unit is chelated by a 1,10-phenanthroline (phen) group and two acetate ligands, one of which also acts as a bridge, linking both seven-coordinated cadmium(II) centres. The crystal structure is governed by a single π-π inter-action between...

In the centrosymmetric binuclear title complex, [Ce(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Ce(III) ions are linked by four 2-phen-oxy-propionate groups in bi- and tridentate bridging modes.
