4-(4-Pyrid-yl)pyridinium penta-aqua(pyridazine-4,5-dicarboxyl-ato)praseodymate(III).

ABSTRACT: In the title complex, (C(10)H(9)N(2))[Pr(C(6)H(2)N(2)O(4))(2)(H(2)O)(5)], the Pr atom is nine-coordinated by nine O atoms from two pyridazine-4,5-dicarboxyl-ate anions and five water mol-ecules. It is noteworthy that there is a protonated bipyridine mol-ecule in the structure. Inter-molecular O-H?O, O-H?N and N-H?N hydrogen bonds are present, resulting in a three-dimensional network.

Project description:In the title compound, (C(10)H(9)N(2))[Fe(C(7)H(3)NO(4))(2)]·4H(2)O or (bpyH)[Fe(pydc)(2)]·4H(2)O, the asymmetric unit contains an [Fe(pydc)(2)](-) (pydcH(2)= pyridine-2,6-dicarboxylic acid) anion, a protonated 4,4'-bipyridine as a counter-ion, (bpyH)(+), and four uncoordinated water mol-ecules. The anion is a six-coordinate complex with a distorted octa-hedral geometry around the Fe(III )atom. A wide range of non-covalent inter-actions, i.e. O-H?O, O-H?N and N-H?O hydrogen bonds, ion pairing, C-O?? [3.431?(2)?Å] and C-H?? stacking inter-actions result in the formation of a three-dimensional network structure.

4-(4-Pyrid-yl)pyridinium bis-(pyridine-2,6-dicarboxyl-ato)chromium(III) tetra-hydrate.

Project description:The title compound, (C(10)H(9)N(2))[Cr(C(7)H(3)NO(4))(2)]·4H(2)O or (4,4'-bipyH)[Cr(pydc)(2)]·4H(2)O (where 4,4'-bipy is 4,4'-bipyridine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of chromium(III) chloride hexa-hydrate with pyridine-2,6-dicarboxylic acid and 4,4'-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic complex, [Cr(pydc)(2)](-), protonated 4,4'-bipyridine as a counter-ion, (4,4'-bipyH)(+), and four uncoordinated water mol-ecules. The anion is a six-coordinate complex with a distorted octa-hedral geometry around the Cr(III) atom, formed by two tridentate pyridine-2,6-dicarboxyl-ate, pydc(2-), groups. Inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and C-O⋯π stacking inter-actions (with distances of 3.3390 (13) and 3.4575 (13) Å) connect the various components into a supra-molecular structure.

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.

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.
