Tetrakis[?-3-(3-pyridyl)acrylato-?O:O']bis{(1,10-phenanthroline-?N,N')[3-(3-pyridyl)acrylato-?O,O']europium(III)} pentahydrate.

ABSTRACT: The europium(III) ion in the title compound, [Eu(2)(C(8)H(6)NO(2))(6)(C(12)H(8)N(2))(2)]·5H(2)O, is coordinated by seven carboxyl-ate O atoms and two N atoms from one phenanthroline mol-ecule. The carboxyl-ate groups of 3-(3-pyrid-yl)acrylate link pairs of europium(III) ions, forming centrosymmetric dinuclear units, which further assemble into a sheet parallel to the (001) plane through hydrogen-bonding inter-actions involving the uncoordinated water mol-ecules. One water molecule is disordered.

Project description:The two independent Ni(II) ions in the one-dimensional title complex, [Ni(2)(C(7)H(3)NO(4))(2)(C(12)H(8)N(4)S)(H(2)O)(2)](n) or [Ni(2)(pydc)(2)(bpt)(H(2)O)(2)](n) (H(2)pydc = pyridine-2,6-dicarboxylic acid and bpt = 2,5-di-4-pyrid-yl-1,3,4-thia-diazole), have different coordination environments. One Ni(II) ion is in a slightly-distorted octa-hedral coordination environment formed by three O atoms from two adjacent pydc ligands, two N atoms from bpt and pydc ligands, and one water mol-ecule, while the other Ni(II) ion is in distorted square-pyramidal geometry, coordinated by two O atoms from two carboxyl-ate groups and two N atoms from the pyridine rings of the pydc and bpt ligands in the basal plane, while a coordinated water mol-ecule occupies the apical site. In the crystal structure, the H atoms of both water mol-ecules are involved in inter-molecular hydrogen bonds with the O atoms of uncoordinated carboxyl-ate groups, which link chains into a three-dimensional network.

The Eu(III) ion is coordinated by nine O atoms from two H(2)bdc ligands, two sulfate anions and three water mol-ecules, displaying a bicapped trigonal prismatic geometry. The carboxyl-ate groups of the H(2)bdc ligands and the sulfate anions link the Eu(III) ions, forming a chain along [010]. These chains are further connected by N-H?O and O-H?O hydrogen bonds and ?-? inter-actions between the imidazole and benzene rings [centroid-centroid distances = 3.997?(4), 3.829?(4) and 3.573?(4)?Å] into a three-dimensional supra-molecular network.

Poly[(?(3)-5-amino-isophthalato-?O,O':O'':O''')[?(2)-1,2-bis-(4-pyrid-yl)ethane-?N:N']cobalt(II)].

Project description:In the title compound, [Co(C(8)H(5)NO(4))(C(12)H(12)N(2))](n), the Co(II) ion presents a distorted CoO(4)N(2) octa-hedral coordination geometry, formed by three 5-amino-isophthalate dianions and two 1,2-bis-(4-pyrid-yl)ethane ligands. One carboxyl-ate group of the 5-amino-isophthalate dianion chelates a Co cation and the other carboxyl-ate group bridges the other two Co cations, while the terminal N atoms of the 1,2-bis-(4-pyrid-yl)ethane ligand coordinate the neighboring Co cations, forming a two-dimensional polymeric architecture. Two pyridine rings of the 1,2-bis-(4-pyrid-yl)ethane ligand are twisted to each other with a dihedral angle of 50.94?(16)°. Weak C-H?O hydrogen bonding and N-H?? inter-actions are observed in the crystal structure. A void of 69?(5)?Å(3) is present in the crystal structure, but no solvent mol-ecule can be located reasonably.

The Eu(III) cation is eightfold coordinated by four carboxyl-ate O atoms, one pyridine N atom, two MeOH and one chloride anion in the form of a distorted polyhedron. Extended coordination of the PDC ligand lead to the formation of a two-dimensional coordination polymer parallel to (10-1).

Project description:In the title complex, [Co(C(10)H(7)O(4))(2)(C(12)H(12)N(2))(H(2)O)(2)](n), the Co(II) ion is located on a crystallographic centre of symmetry and is six-coordinated by two N atoms from two 1,2-bis-(4-pyrid-yl)ethane ligands, two carboxylate O atoms from two 1,3-dihydro-3-oxo-1-isobenzofuran-acetate ligands and two terminal water ligands. The 1,2-bis(4-pyrid-yl)ethane ligands act as bidentate ligands, and bridge the Co(II) ions into infinite chains extending parallel to [010]. In these chains, there are intra-mol-ecular O-H?O hydrogen bonding between the coordination water mol-ecules and carboxyl-ate groups. Inter-mol-ecular O-H?O hydrogen bonding between the adjacent chains and ??? stacking inter-actions result in the formation of a three-dimensional supra-molecular network.
