Poly[hydrazin-1-ium [diaqua-bis-(?(4)-pyridazine-3,6-dicarboxyl-ato)trilithate] monohydrate].

ABSTRACT: The structure of the title compound, {(N(2)H(5))[Li(3)(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·H(2)O}(n), is composed of mol-ecular dimers, each built up of two symmetry-related Li(I) ions with distorted trigonal-bipyramidal coordinations bridged by two deprotonated ligand mol-ecules via their N,O-bonding sites. Doubly solvated Li(I) ions with a distorted tetra-hedral geometry link adjacent dimers, forming a polymer generated by bridging bidentate carboxyl-ato O atoms to Li(I) ions in adjacent dimers, forming anionic layers parallel to the ac plane with monoprotonated hydrazinium cations and crystal water mol-ecules positioned between them. The layers are held together by an extended system of hydrogen bonds in which the hydrazinium cations and coordinated and crystal water mol-ecules act as donors and carboxyl-ate O atoms act as acceptors.

Project description:The unit cell of the title compound, (N(2)H(5))(2)[Li(2)(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·[Li(4)(C(6)H(2)N(2)O(4))(2)(H(2)O)(8)], comprises two centrosymmetric complexes, one double negatively charged and one neutral, and two mono-protonated hydrazine cations. The anionic complex molecule is a dimer, built of a pair of symmetry-related pyridazine-3,6-dicarboxyl-ate ligands and a pair of Li(I) ions, each coordinated by two N,O-chelating sites donated by a ligand mol-ecule and an aqua O atom at the apical position. The penta-coordination around the Li(I) ions is partway between a trigonal-bipyramidal and a square-pyramidal arrangement. The two carb-oxy-lic acid groups of the ligand are deprotonated and one carboxyl-ate O atom of each group is not involved in the coordination, and this applies to both the anionic and the neutral complex. The neutral complex molecule is also composed of a pair of Li(I) ions and a pair of ligand mol-ecules related by a centre of symmetry. They form a dimeric core in which the penta-coordination of the Li(I) ions includes two N,O-bonding groups donated by two ligands and an aqua O atom. The penta-coordination is described as partway between a trigonal-bipyramidal and a square-pyramidal arrangement. The coordinated carboxyl-ate group is bidentate-bridging, forming with an Li(H(2)O)(3) unit a neutral tetra-meric mol-ecule. The coordination of the tetra-coordinated Li(I) ion shows a slightly distorted tetra-hedral geometry. An extended system of O-H?O and N-H?O hydrogen bonds contributes to the stability of the crystal structure.

catena-Poly[[?(2)-aqua-diaqua-bis-(?(4)-pyridazine-3,6-dicarboxyl-ato)tetra-lithium] monohydrate].

Project description:In the polymeric structure of the title compound {[Li(2)(C(6)H(2)N(2)O(4))(2)Li(H(2)O)(2)Li(H(2)O)]·H(2)O}(n), the coordination of two independent Li(I) ions is distorted trigonal-bipyramidal and that of the other two independent Li(I) ions is distorted tetra-hedral. The former two Li(I) ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxyl-ate ligands, making a dimeric moiety. The carboxyl-ato-O atoms of both bidentate ligands bridge the dimers to adjacent independent aqua-coordinated Li(I) ions, forming mol-ecular ribbons. The latter are bridged by ligand carboxyl-ato and aqua O atoms, forming mol-ecular layers parallel to (100) which are held together by an extended system of O-H?O hydrogen bonds.

Project description:The title compound, {[Mn(2)(C(7)H(3)NO(4))(2)(C(2)H(5)OH)(H(2)O)(2)]·H(2)O}(n), is a three-dimensional polymer.

The crystal structure is stabilized by O-H?O hydrogen bonds.

catena-Poly[diimidazolium [bis-(?-pyridine-2,5-dicarboxyl-ato)bis-[diaqua-praseodymate(III)]]-bis-(?-pyridine-2,5-dicarboxyl-ato)].

Project description:The title compound {(C(3)H(5)N(2))(2)[Pr(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]}(n), has a chain structure featuring a dimeric unit consisting of two Pr(III) atoms within a dodecahedral environment. Each of the metal cations is coordinated by two N atoms and two O atoms from two pyridine-2,5-dicarboxyl-ate ligands, two O atoms from another two pyridine-2,5-dicarboxyl-ate ligands and two water O atoms. The Pr(III) ions are bridged by two ligands along the c axis, forming the dimeric unit, and these are connected by four ligands along the b axis, forming a chain. N-H?O and O-H?O hydrogen bonds are found in the structure.

3-(Amino-carbon-yl)pyridinium diaqua-bis-(pyridine-2,6-dicarboxyl-ato)bis-muthate(III) monohydrate.

Project description:The asymmetric unit of the ionic title compound, (C(6)H(7)N(2)O)[Bi(C(7)H(3)NO(4))(2)(H(2)O)(2)]·H(2)O or (acpyH)[Bi(pydc)(2)(H(2)O)(2)]·H(2)O, contains an [Bi(pydc)(2)(H(2)O)(2)](-) anion (where pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid), a protonated 3-(amino-carbon-yl)pyridine as counter-ion, (acpyH)(+), and one uncoordinated water mol-ecule. The anion is an eight-coordinate complex with a square-anti-prismatic geometry around the Bi(III) atom. In the crystal, extensive O-H?O and N-H?O hydrogen bonds, as well as ion pairing, C=O?? inter-actions [O?centroid distance = 3.583?(5)?Å], ?-? stacking [centroid-centroid distance = 3.864?(3)?Å], and C-H?? and C-H?O inter-actions, play an important role in the formation and stabilization of the three-dimensional supra-molecular structure.

Poly[[diaqua-[?(4)-4,4'-carbonyl-bis(benzene-1,2-dicarboxyl-ato)]bis-(dipyrido[3,2-a:2',3'-c]phenazine)dicadmium(II)] monohydrate].

Project description:In the title compound, {[Cd(2)(C(17)H(6)O(9))(C(18)H(10)N(4))(2)(H(2)O)(2)]·H(2)O}(n), the Cd(II) atom is seven-coordinated by five O atoms from two different 4,4'-carbonyl-bis(benzene-1,2-dicarboxyl-ate) (BPTC) anions and one water mol-ecule, and by two N atoms from one chelating dipyrido[3,2-a:2',3'-c]phenazine (L) ligand in a distorted penta-gonal-bipyramidal geometry. The BPTC anions link the Cd(II) atoms, forming a one-dimensional chain structure. The L ligands are attached on both sides of the chain. A twofold rotation axis passes through the complex molecule. The crystal structure involves O-H?O hydrogen bonds.

Poly[[diaqua-(?(4)-1H-benzimidazole-5,6-dicarboxyl-ato)strontium] monohydrate].

Project description:Each of the carboxyl-ate -CO(2) fragments of the dianion ligand in the title compound, {[Sr(C(9)H(4)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), chelates to a Sr(II) atom and at the same time, one of the two O atoms coordinates to a third Sr(II) atom. The ?(4)-bridging mode of the dianion generates a square-grid layer motif; adjacent layers are connected by O-H?O, O-H?N and N-H?O hydrogen bonds, forming a three-dimensional network. The eight-coordinate Sr atom exists in a distorted square-anti-prismatic geometry. The crystal studied was a non-merohedral twin with a minor twin component of 24%.

Poly[diaqua-bis-(?(3)-1H-imidazole-4,5-dicarboxyl-ato)(?(2)-sulfato)-diytterbium(III)].

Project description:In the title compound, [Yb(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(H(2)O)(2)](n), the Yb(III) ion is eight-coordinated by four O atoms and one N atom from three imidazole-4,5-dicarboxyl-ate ligands, two O atoms from one SO(4) (2-) anion (site symmetry 2), as well as one O atom of a water mol-ecule, giving a bicapped trigonal-prismatic coordination geometry. The metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate and sulfate ligands, generating a heterometallic layer. The layers are stacked along the a axis via N-H?O, O-H?O, and C-H?O hydrogen-bonding inter-actions, generating a three-dimensional framework.

Poly[diaqua-(?(5)-pyridine-3,5-dicarboxyl-ato)strontium].

Project description:In the structure of the title compound, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) cation is eight-coordinated in form of a distorted dodeca-hedron by two water O atoms and by five O atoms and one N atom from five pyridine-3,5-dicarboxyl-ate anions. The bridging mode of the anions leads to the formation of a layered network parallel to (100). O-H?O hydrogen bonding between the coordinating water mol-ecules and the carboxyl-ate groups of adjacent layers consolidates the crystal packing. Weak C-H?O inter-actions are also observed.
