Poly[tetra-?(1,1)-azido-bis-(?(2)-pyrimidine-2-carboxyl-ato)tricopper(II)].

ABSTRACT: In the title compound, [Cu(3)(C(5)H(3)N(2)O(2))(2)(N(3))(4)](n), one of the Cu(II) atoms lies on an inversion centre and is octa-hedrally coordinated by two bidentate chelating pyrimidine-2-carboxyl-ate ligands and two azide anions, each of which gives an N:N-bridge to the second inversion-related Cu(II) centre in the formula unit. The second Cu(II) atom is five-coordinated with a distorted square-pyramidal coordination sphere comprising a single bidentate chelating pyrimidine-2-carboxyl-ate anion and three azide N anions, two of which doubly bridge centrosymmetric Cu(II) centres, giving a two-dimensional network structure extending parallel to (010).

Bis(?(3)-pyrimidine-4-carboxyl-ato)bis-(?(2)-pyrimidine-4-carboxyl-ato)tetra-kis-(aqua-lithium).

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(4)(H(2)O)(4)], contains two symmetry-independent Li(I) ions, two symmetry-independent ligands and two symmetry-independent coordinated water mol-ecules. They form a dinuclear unit in which the two Li(I) ions are bridged by two carboxyl-ate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetra-meric mol-ecule. One of the Li(I) ions shows a distorted tetra-hedral coordination geometry, the other a distorted trigonal-bipyramidal environment. The tetra-mers are held together by hydrogen bonds in which coordinated water mol-ecules act as donors, and the carboxyl-ate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

catena-Poly[[tetra-aqua-?-aqua-bis-(?(4)-pyrimidine-2-carboxyl-ato)tetra-lithium] dichloride].

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(2)(H(2)O)(5)]Cl(2), contains two Li(I) cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetra-hedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxyl-ate O atoms are bidentate and bridge the metal ions, forming a divalent cation. Charge balance is maintained by two chloride anions. The building blocks, bridged by Li(I) cations, form cationic ribbons with chloride anions in the space between them. The ribbons propagate in [010] and are held together by a network of weak O-H?O hydrogen bonds which operate in the space between adjacent ribbons.

Octa-aqua-bis(μ(2)-1H-pyrazole-3,5-di-carboxyl-ato)tricopper(II) tetra-hydrate.

Project description:In the trinucler Cu(II) complex mol-ecule of the title compound, [Cu(3)(C(5)HN(2)O(4))(2)(H(2)O)(8)]·4H(2)O, the central Cu(II) atom is located on an inversion centre and is coordinated in a distorted octa-hedral geometry. The equatorial sites are occupied by two N and two O atoms from two pyrazole-3,5-dicarboxyl-ate ligands and the axial positions are occupied by two water mol-ecules. The two other symmetry-related Cu(II) atoms are penta-coordinated and assume a square-pyramidal geometry. In the crystal structure, coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms are linked by O-H⋯O hydrogen bonds.

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Poly[(?(6)-benzene-1,2,4,5-tetra-carboxyl-ato)bis-(1,10-phenanthroline-?N,N')dimanganese(II)].

Project description:The title polymeric compound, [Mn(2)(C(10)H(2)O(8))(C(12)H(8)N(2))(2)](n), was obtained by the reaction of manganese(II) chloride tetra-hydrate with benzene-1,2,4,5-tetra-carboxylic acid (H(4)bta) in aqueous solution. Each Mn(2+) ion is coordinated in a distorted octa-hedral geometry by two N atoms from one 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.116?(2)-2.237?(2)?Å] from three bta(4-) ligands, which also act as bridging groups between the Mn(2+) ions.

Poly[hexa-aqua-bis-(?(4)-pyrimidine-4,6-dicarboxyl-ato)tetra-lithium].

Project description:The asymmetric unit of the title compound, [Li(4)(C(6)H(2)N(2)O(4))(2)(H(2)O)(6)](n), comprises two Li(+) ions bridged by a completely deprotonated pyrimidine-3,6-dicarboxyl-ate ligand and coordinated by two water mol-ecules; the asymmetric units related by an inversion operation create a structural unit which forms part of a two-dimensional polymeric structure parallel to (10-1). One of the Li(+) ions shows a distorted tetra-hedral arrangement involving two symmetry-related coordinating water mol-ecules and two carboxyl-ate O atoms. The other Li(+) ion is in distorted trigonal-bipyramidal geometry defined by N and O atoms of the ligands and a water mol-ecule. Water O atoms are proton donors to carboxyl-ate O atoms forming hydrogen bonds.

Poly[bis-(?(2)-pyrimidine-2-carboxyl-ato-?O,N:O',N')calcium].

Project description:In the crystal structure of the title polymeric complex, [Ca(C(5)H(3)N(2)O(2))(2)](n), the Ca(II) cation has site symmetry m2 and is N,O-chelated by four pyrimidine-2-carboxyl-ate anions in a square-anti-prismatic geometry. The planar pyrimidine-2-carboxyl-ate anion is located on a crystallographic special position, three C atoms have site symmetry 2mm, while the carboxyl O atom, the pyrimidine N atom and the other C atom have site symmetry m. Each pyrimidine-2--carboxyl-ate anion bridges two Ca(II) cations, forming polymeric sheets extending parallel to (001). ?-? stacking exists between parallel pyrimidine rings [centroid-centroid distance = 3.6436?(6)?Å] of adjacent polymeric sheets. Weak C-H?O hydrogen bonding is also observed between these sheets.

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.

Project description:In the title complex, [Zn(C(10)H(6)N(3)O(2))(2)(H(2)O)(4)], the Zn(II) ion lies on an inversion center and is coordinated in a slightly distorted octa-hedral geometry by two N atoms from two 2-(pyridin-4-yl)pyrimidine-5-carboxyl-ate ligands and four water mol-ecules. In the symmetry-unique part of the mol-ecule, the pyridine and pyrimidine rings form a dihedral angle of 7.0?(1)°. In the crystal, the coordinating water mol-ecules act as donor groups and carboxyl-ate O atoms act as acceptors in O-H?O hydrogen bonds, forming a three-dimensional network.
