Dipyridinium diaqua-bis-(pyrazole-3,5-di-carboxyl-ato-?(2) N,O)cuprate(II) dihydrate.

ABSTRACT: In the mononuclear title salt, (C5H6N)2[Cu(C5H2N2O4)2(H2O)2]·2H2O, the Cu(II) ion is located on an inversion centre and is coordinated by two chelating pyrazole-3,5-dicarboxyl-ate anions and two water mol-ecules, forming a Jahn-Teller-distorted CuN2O4 octa-hedron. O-H?O and N-H?O hydrogen bonds are formed between water mol-ecules, complex anions and the pyridine counter-cations, leading to the formation of layers parallel to (100). The layers are held together by weak C-H?O hydrogen bonds.

In the mononuclear title salt, (C5H6N)2[Cu(C5H2N2O4)2(H2O)2]·2H2O, the Cu(II) ion is located on an inversion centre and is coordinated by two chelating pyrazole-3,5-dicarboxyl-ate anions and two water mol-ecules, forming a Jahn-Teller-distorted CuN2O4 octa-hedron. O-H⋯O and N-H⋯O hydrogen bonds are formed between water mol-ecules, complex anions and the pyridine counter-cations, leading to the formation of layers parallel to (100). The layers are held together by weak C-H⋯O hydrogen bonds. ...[more]

Poly[[hexa-?-aqua-diaqua-bis-(??-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa?(C??H?O?)?(H?O)?]·2H?O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by ??-bridging btec ligands, which form inter-molecular O-H?O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H?O hydrogen bonds.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

Tetra-aqua-bis(1,10-phenanthroline)bis-[?(2)-1H-pyrazole-3,5-dicarboxyl-ato(3-)]tricopper(II) dihydrate.

Project description:The title compound, [Cu(3)(C(5)HN(2)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, is a trinuclear copper(II) complex in which two centrosymmetrically related pyrazole-3,5-dicarboxyl-ate(3-) and 1,10-phenanthroline ligands bind three Cu(II) atoms, with one Cu(II) atom located on a center of symmetry. In each complex, there are four coordinated water mol-ecules and two solvent water mol-ecules, which participate in extensive hydrogen-bond patterns. These inter-actions, as well as ?-? inter-actions between neighbouring 1,10-phenanthroline ligands [shortest atom-to-atom distance = 3.363?(3)?Å], extend the crystal structure into a three-dimensional supra-molecular network.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38 Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87 (2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, O-H⋯O and N-H⋯O hydrogen bonds.

Di-?-aqua-bis-(?-pyridazine-4-carboxyl-ato-?N:N')bis-[triaqua-(pyridazine-4-carboxyl-ato-?O,O')lead(II)] dihydrate.

Project description:The structure of the title compound, [Pb(2)(C(5)H(3)N(2)O(2))(4)(H(2)O)(6)]·2H(2)O, is composed of dimeric mol-ecules in which two symmetry-related Pb(2+) ions are bridged by a pair of two pyridazine-4-carboxyl-ate ligand mol-ecules via both heterocyclic N atoms and two water O atoms. Each Pb(2+) ion is also coordinated by two carboxyl-ate O atoms and three water O atoms, leading to a highly irregular coordination polyhedron around Pb(2+). The dimers are inter-connected by hydrogen bonds between coordinated and uncoordinated water mol-ecules and the carboxyl-ate O atoms. O-H?N inter-actions are also present.

1,1'-(Ethane-1,2-di-yl)dipyridinium bis-(1,2-di-cyano-ethene-1,2-di-thiol-ato-κ(2) S,S')cuprate(II).

Project description:In the title ion-pair complex, (C12H14N2)[Cu(C4N2S2)2], the complex anion exhibits a highly twisted coordination environment around the tetra-coordinated Cu(II) atom. The dihedral angles between the 1,2-di-cyano-ethene-1,2-di-thiol-ato ligands and between the two pyridine rings in the cation are 37.49 (3) and 29.18 (10)°, respectively. Weak C-H⋯N and C-H⋯S hydrogen bonds link the cations and anions into a three-dimensional network.
