Bis(?-3-carb-oxy-2-hy-droxy-propane-1,2-dicarboxyl-ato)bis(diaquazinc)-1,2-bis-(pyridin-4-yl)ethene-water (1/1/2).

ABSTRACT: The asymmetric unit of the title compound, [Zn(2)(C(6)H(6)O(7))(2)(H(2)O)(4)]·C(12)H(10)N(2)·2H(2)O, comprises half of a centrosymmetric complex dimer, half of a 1,2-bis-(pyridin-4-yl)ethene mol-ecule, which lies across an inversion centre, and one lattice water mol-ecule. Carboxyl-ate groups of two dianionic citrate ligands bridge two Zn(II) ions to give the cyclic dimer, with each Zn(II) ion coordinated by four O atoms from the chelating citrate ligand (one hy-droxy and three carboxyl-ate, with one bridging) and two water O atoms, forming a distorted octa-hedral environment [Zn-O = 2.040?(3)-2.244?(3)?Å]. In the crystal, O-H?O and O-H?N hydrogen bonds involving hy-droxy groups and both coordinating and lattice water mol-ecules link the dimers to give a three-dimensional framework structure.

Bis(?-2-carb-oxy-methyl-2-hy-droxy-butane-dioato)bis-[diaqua-manganese(II)]-1,2-bis-(pyridin-4-yl)ethene-water (1/1/2).

Project description:The asymmetric unit of the title compound, [Mn2(C6H6O7)2(H2O)4]·C12H10N2·2H2O, contains half of the centrosymmetric Mn complex dimer, half of a 1,2-bis-(pyridin-4-yl)ethene mol-ecule, which lies across an inversion center, and one water mol-ecule. Two citrate ligands bridge two Mn(II) ions, and each Mn(II) atom is coordinated by four O atoms from the citrate ligands (one from hy-droxy and three from carboxyl-ate groups) and two water O atoms, forming a distorted octa-hedral environment. In the crystal, O-H?O and O-H?N hydrogen bonds link the centrosymmetric dimers and lattice water mol-ecules into a three-dimensional structure which is further stabilized by inter-molecular ?-? inter-actions [centroid-centroid distance = 3.959?(2)?Å]. Weak C-H?O hydrogen bonding interactions are also observed.

Bis(8-hy-droxy-1-methyl-quinolin-1-ium) bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II) dihydrate.

Project description:In the title ion-pair complex, (C(10)H(10)NO)(2)[Ni(C(4)N(2)S(2))(2)]·2H(2)O, the anion has crystallographically imposed centre of symmetry. The Ni(II) atom exhibits a slightly distorted square-planar coordination geometry. In the crystal, the water mol-ecule links anions and cations into a three-dimensional network via O-H?N, O-H?S and O-H?O hydrogen bonds. The structure is further stabilized by weak S?? contacts [S?centroid = 3.8047?(9)?Å] and ?-? stacking inter-actions [centriod-centroid distance = 3.8653?(7)?Å].

?-4,4'-Bipyridine-bis-[aqua-(4-hy-droxy-pyridine-2,6-dicarboxyl-ato)copper(II)].

Project description:The title compound, [Cu(2)(C(7)H(3)NO(5))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a centrosymmetric binuclear molecule. Each completely deprotonated 4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid mol-ecule assumes a tridentate chelating coordination mode. The square-pyramidal coordination geometry around the Cu(II) ion is completed by the bridging bipyridine ligand and an apical water molecule. Adjacent complexes are connected via O-H?O and C-H?O hydrogen bonds to generate a three-dimensional supra-molecular structure.

Project description:The reaction of nickel(II) nitrate hexa-hydrate, propane-1,2-diamine and pyridine-2,6-dicarboxylic acid in a 1:2:2 molar ratio in aqueous solution resulted in the formation of the title compound, (C(3)H(12)N(2))[Ni(C(7)H(3)NO(4))(2)]·4H(2)O or (p-1,2-daH(2))[Ni(pydc)(2)]·4H(2)O (where p-1,2-da is propane-1,2-diamine and pydcH(2) is pyridine-2,6-dicarboxylic acid). The geometry of the resulting NiN(2)O(4) coordination can be described as distorted octa-hedral. Considerable C=O?? stacking inter-actions are observed between the carboxyl-ate C=O groups and the pyridine rings of the (pydc)(2-) fragments, with O?? distances of 3.1563?(12) and 3.2523?(12)?Å and C=O?? angles of 95.14?(8) and 94.64?(8)°. In the crystal structure, a wide range of non-covalent inter-actions, consisting of hydrogen bonding [O-H?O, N-H?O and C-H?O, with D?A distances ranging from 2.712?(2) to 3.484?(2)?Å], ion pairing, ?-? [centroid-to-centroid distance = 3.4825?(8)?Å] and C=O?? stacking, connect the various components to form a supra-molecular structure.

Bis(8-hy-droxy-2-methyl-quinolinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) methanol monosolvate monohydrate.

Project description:The title compound, (C(10)H(10)NO)(2)[Cu(C(7)H(3)NO(4))(2)]·CH(3)OH·H(2)O was prepared by the reaction of copper(II) nitrate hexa-hydrate, 8-hy-droxy-2-methyl-quinoline, and pyridine-2,6-dicarb-oxy-lic acid in a 1:2:2 molar ratio in an aqueous solution. The geometry of the resulting CuN(2)O(4) coordination can be described as distorted octa-hedral. In the crystal, there are several inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. An intra-molecular N-H⋯O hydrogen bond occurs in one of the cations. Considerable π-π stacking inter-actions are also observed between the aromatic rings of the cations, with centroid-centroid distances of 3.4567 (13), 3.5342 (14), 3.6941 (14) and 3.4568 (13) Å. These non-covalent inter-actions connect the components, forming a three-dimensional supra-molecular structure.

Poly[[bis-[?2-1,2-bis-(pyridin-4-yl)ethene-?(2) N:N']bis-(thio-cyanato-?N)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate dihydrate].

Project description:The asymmetric unit of the title compound, {[Co(NCS)2(C12H10N2)2]·C12H10N2·2H2O} n , consists of two independent Co(II) cations, four distinct thio-cyanate anions, six 1,2-bis-(pyridin-4-yl)ethene (4-bpe) mol-ecules and four lattice water mol-ecules. The Co(II) cations are each coordinated by two N-bonded thio-cyanate anions and four 4-bpe ligands within a slightly distorted CoN6 octa-hedron. The two independent Co(II) cations are linked by the 4-bpe ligands into two distinct layers, parallel to the ac and bc planes, that inter-penetrate. From this arrangement, channels are formed in which non-coordinated 4-bpe and lattice water mol-ecules are hydrogen-bonded into chains that elongate in the c-axis direction.

[?-1,2-Bis(4-pyrid-yl)ethene-?N:N']bis-[aqua-(pyridine-2,6-dicarboxyl-ato-?O,N,O)copper(II)] dihydrate.

Project description:In the title dinuclear Cu(II) complex, [Cu(2)(C(7)H(3)NO(4))(2)(C(12)H(10)N(2))(H(2)O)(2)]·2H(2)O, the water-coordinated Cu(II) cation is O,N,O'-chelated by a pyridine-2,6-dicarboxyl-ate (pdc) dianion, and one pyridine N atom from a 1,2-bis-(4-pyrid-yl)ethene ligand coordinates to the Cu(II) cation, completing the CuN(2)O(3) distorted square-pyriamidial geometry. The Cu-O(water) bond [2.388?(4)?Å] in the axial direction is much longer than the other Cu-O bonds. The 1,2-bis-(4-pyrid-yl)ethene ligand is located across an inversion center with the mid-point of the C=C bond at the inversion center, and bridges two Cu(II) cations, generating a centrosymmetric dinuclear complex. The crystal structure is stabilized by classical O-H?O and weak C-H?O hydrogen bonds.
