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

ABSTRACT: 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.

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.

cyclo-Tetra-kis(μ-3-acetyl-4-methyl-1H-pyrazole-5-carboxyl-ato-κN,O:N,O)tetra-kis[aqua-copper(II)] tetra-deca-hydrate.

Project description:The title compound, [Cu(4)(C(7)H(6)N(2)O(3))(4)(H(2)O)(4)]·14H(2)O, a tetra-nuclear [2 × 2] grid-type complex with S4 symmetry, contains four Cu(II) atoms which are bridged by four pyrazole-carboxyl-ate ligand anions and are additionally bonded to a water molecule. Each Cu(II) atom is coordinated by two O atoms of the carboxyl-ate and acetyl groups, two pyrazole N atoms of doubly deprotonated 3-acetyl-4-methyl-1H-pyrazole-5-carb-oxy-lic acid and one O atom of a water mol-ecule. The geometry at each Cu(II) atom is distorted square-pyramidal, with the two N and two O atoms in the equatorial plane and O atoms in the axial positions. O-H⋯O hydrogen-bonding interactions additionally stabilize the structure. One of the uncoordinated water molecules shows half-occupancy.

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

Project description: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).

catena-Poly[[tetra-aqua-μ-aqua-bis-(μ(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.

Bis-(μ-pyridine-2,3-dicarboxyl-ato)bis-[aqua-(3-carb-oxy-pyridine-2-carboxyl-ato)indium(III)] tetra-hydrate.

Project description:In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]·4H(2)O, which contains both pyridine-2,3-dicarboxyl-ate and 3-carb-oxy-pyridine-2-carboxyl-ate ligands, the In(III) atom is six-coordinated in a distorted octa-hedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H⋯O hydrogen-bonding network, involving the coordinated and lattice water mol-ecules and the carboxyl groups of the ligands, together with C-H⋯O and π-π inter-actions [centroid-centroid distance = 3.793 (1) Å], leads to the formation of a three-dimensional structure.

Poly[octa-μ-aqua-tetra-aqua-bis(μ(4)-5-sulfonatobenzene-1,3-dicarboxyl-ato)nickel(II)tetra-sodium].

Project description:In the crystal structure of the title compound, [Na(4)Ni(C(8)H(3)O(7)S)(2)(H(2)O)(12)](n), the Ni(II) cation occupies an inversion centre and is coordinated by the carboxyl groups of the sulfoisophthalate trianions and water mol-ecules in a distorted octa-hedral geometry.

Weak π-π stacking is present between parallel benzene rings [centroid-centroid distance = 3.9349 (10) Å]. Extensive O-H⋯O and C-H⋯O hydrogen bonding helps to stabilize the crystal structure.

Project description:The title compound, [CoNa(4)(C(8)H(3)O(7)S)(2)(H(2)O)(12)](n), is a three-dimensional coordination polymer bridged by sulfoisophthalate trianions and water mol-ecules.

Poly[tetra-aqua-μ(3)-pyridine-3,5-dicarboxyl-ato-strontium(II)].

Project description:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol-ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca-hedron. These binuclear units are connected via the carboxyl-ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter-actions consisting of hydrogen bonds (X-H⋯O, with X = O and C) and π-π stacking inter-actions [3.4604 (19) Å] connect the various components to form a supra-molecular structure.

catena-Poly[[octa-aqua-bis-(?(4)-benzene-1,3,5-tricarboxyl-ato)trizinc] tetra-hydrate].

Project description:In the title compound, {[Zn(3)(C(9)H(3)O(6))(2)(H(2)O)(8)]·4H(2)O}(n), there are two crystallographically independent Zn(II) ions. One presents a trigonal-bipyramidal coordination geometry defined by five O atoms [three from two carboxyl-ate groups of two benzene-1,3,5-tricarboxyl-ate (BTC) ligands and the other two deriving from three water mol-ecules], while the other lies on an inversion centre and exists in a slightly distorted octa-hedral coordination geometry defined by six O atoms (two from two carboxyl-ate groups of two BTC ligands and the others from four water mol-ecules). A three-dimensional framework is further strengthened via O-H?O hydrogen-bonding inter-actons.
