Poly[[diaqua-?(6)-succinato-di-?(5)-succinato-didysprosium(III)] mono-hydrate].

ABSTRACT: The title compound, {[Dy(2)(C(4)H(4)O(4))(3)(H(2)O)(2)]·H(2)O}(n), is isostructural with other lanthanide succinates of the same formula. The Dy(III) atom is nine-coordinated in a tricapped trigonal-prismatic environment by eight O atoms, derived from six carboxyl-ate groups and a water mol-ecule. One of the independent succinate anions is located about a crystallographic inversion center and the uncoordinated water mol-ecule lies on a twofold axis. The crystal structure comprises edge-shared DyO(9) polyhedra linked by succinate bridges, forming a three-dimensional network architecture. Intra- and inter-molecular O-H?O hydrogen bonds are present in the crystal structure.

Project description:In the title coordination complex, {[Cd(C(10)H(8)O(6))(H(2)O)(2)]·H(2)O}(n) the Cd(II) atom is seven-coordinated in a distorted penta-gonal-bipyramidal geometry, the penta-gonal plane comprising four O-atom donors from the 2,2'-(1,2-phenyl-enedi-oxy)diacetate chelate ligand together with a bridging carboxyl-ate O-atom donor, with the axial sites occupied by two water mol-ecules. The resulting helical chains extend along the b axis and are inter-connected by extensive O-H?O hydrogen-bonding inter-actions, which also involve the water mol-ecule of solvation, giving a three-dimensional structure.

Project description:In the title compound, [Lu(2)(C(8)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the Lu(3+) cations are each coordinated by eight O atoms of four terephthalate anions, one oxalate anion and one aqua ligand to complete a distorted square-anti-prismatic geometry. They are bridged by the terephthalate ligands, generating a three-dimensional framework, which is further stabilized by the oxalate ligands.

Project description:In the asymmetric unit of the title coordination polymer, {[CoNa(C(10)H(12)N(2)O(8))(H(2)O)(2)]·2H(2)O}(n), the Co(II) ion is coord-inated in a distorted octa-hedral environment, defined by two N atoms and four carboxyl-ate O atoms. Two Co(II) ions and two 2-({2-[(1,2-dicarboxyl-atoeth-yl)amino]-eth-yl}amino)-butane-dio-ate (EDDS) ligands form a dimeric complex dianion [Co(2)(EDDS)(2)]. These dimeric units are connected via Na(+) ions, forming a three-dimensional polymeric structure. In the crystal, the ligand N-H groups and the coordinated and solvent water mol-ecules are involved in inter-molecular N-H⋯O and O-H⋯O hydrogen bonding, reinforcing the three-dimensional polymeric structure.

Project description:The crystal structure of the title complex, [Yb(2)(C(8)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), features an extended three-dimensional framework made up of Yb(3+) ions coordinated by terephthalate ligands, oxalate ligands and water mol-ecules. The Yb(3+) ion has a distorted square-anti-prismatic coordination formed by one aqua ligand, two O atoms from an oxalate ligand and five O atoms belonging to four terephthalate anions. Two symmetry-independent terephthalate anions, as well as the oxalate anion, occupy special positions on inversion centers. The water molecule participates in O-H⋯O hydrogen bonding with both terephthalate anions.

Project description:In the title compound, [Y(2)(C(4)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the flexible succinate anion assumes a gauche conformation and bridges the eight-coordinated Y atoms, generating two-dimensional layers parallel to (010). The coordination polymer layers are linked into a three-dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion. Inter-molecular O-H⋯O hydrogen bonds help to stabilize the crystal structure.

Project description:In the crystal structure of the title compound, {[Ni(C(4)H(2)O(4))(C(10)H(9)N(3))(H(2)O)(2)]·4H(2)O}(n), zigzag chains are built up from cis-[Ni(dpya)(H(2)O)(2)](2+) cations (dpya is di-2-pyridylamine) linked by bis-monodentate coordinated bridging fumarate ligands. The Ni(II) atom is coordinated by one chelating dpya ligand, two aqua ligands in trans positions and two monodentate fumarate ligands in cis positions in the form of a deformed octa-hedron. The water mol-ecules, O atoms of the fumarate carboxyl-ate groups and the amine group of the dpya ligand are involved in an extended network of intra- and inter-molecular O-H?O hydrogen bonds. Moreover, ?-? inter-actions between the pyridine rings of the dpya ligand contribute to the stability of the structure. Two of the five uncoordinated water molecules are half-occupied.

Project description:In the title compound, {[Co(C(10)H(14)N(4))(2)(H(2)O)(2)]Cl(2)·4H(2)O}(n), the Co(II) atom and the mid-point of the 1,1'-butane-1,4-diyl-diimidazole ligands lie on inversion centers. The Co(II) atom is six-coordinated in a slightly distorted octa-hedral environment by four N atoms from four different ligands and by two O atoms from the water mol-ecules. The Co(II) atoms are bridged by the ligands into a (4,4) net. Adjacent nets are linked to the chloride anions and uncoordinated water mol-ecules via O-H⋯Cl and O-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.
