Poly[diaqua-μ-oxalato-μ-pyrazine-2-carboxylato-lanthanum(III)]
In the title complex, [La(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by one N and three O atoms from two pyrazine-2-carboxylate ligands, by four O atoms from two oxalate ligands and by two O atoms of two water molecules, displaying a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups of pyrazine-2-carboxyl-ate and oxalate ligands link the l...

In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In th...
متن کاملμ-Pyrazine-bis[tetraaquacadmium(II)] μ-pyrazine-bis[tetraacetatocadmium(II)]
In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the ...
متن کاملDi-μ-azido-diazidodi-μ-oxalato-dihistaminetetracopper(II) 0.9-hydrate
The title compound, [Cu4(C2O4)2(N3)4(C5H9N3)2]·0.9H2O, contains a tetranuclear Cu(II)-based molecule composed of two oxalate-bridged Cu(II) dimers linked through end-on azide ions and related by an inversion center. The tetranuclear unit contains two crystallographically independent Cu(II) ions. One Cu(II) ion coordinates to two N atoms of a histamine mol-ecule, two O atoms of a bridging oxalat...
متن کاملPoly[μ-5-ammonioisophthalato-aqua-μ-oxalato-dysprosium(III)]
The title complex, [Dy(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a dysprosium coordination polymer with mixed anions and was obtained under hydrothermal conditions. In the structure, the oxalate and 5-amino-isophthalate ligands link the dysprosium ions, building up a two-dimensional metal-organic framework parallel to the (10) plane. These sheets are further connected through O-H⋯O, N-H⋯O and C-H...
