Poly[[diaqua-hemi-?(4)-oxalato-?(2)-oxalato-praseodymium(III)] monohydrate].

ABSTRACT: In the title complex, {[Pr(C(2)O(4))(1.5)(H(2)O)(2)]·H(2)O}(n), the Pr(III) ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr-O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occupying space in small voids and being secured by O-H?O hydrogen bonding as an acceptor from ligand water H atoms and as a donor to oxalate O-acceptor sites.

Poly[hemi(ethyl-enediammonium) [di-?-oxalato-indium(III)] dihydrate].

Project description:In title compound, {(C(2)H(10)N(2))(0.5)[In(C(2)O(4))(2)]·2H(2)O}(n), the unique In(III) ion is coordinated by eight O atoms from four oxalate ligands in a distorted square-anti-prismatic environment. The doubly bis-chelating oxalate ligands act as bridging ligands connecting symmetry-related In(III) ions and forming a three-dimensional open framework structure. Ethyl-enediammonium cations and water mol-ecules occupy the voids within the structure. The unique ethyl-enediammonium cation and one water mol-ecule both lie on a twofold rotation axis. One of the other two water mol-ecules residing on general crystallographic sites was refined as disordered with half occupancy. In the crystal structure, cations and water mol-ecules are linked to the anionic framework via inter-molecular O-H?O and N-H?O hydrogen bonds.

Poly[[diaqua-?(3)-citrato-praseodymium(III)] monohydrate].

Project description:In the coordination polymer, {[Pr(C(6)H(5)O(7))(H(2)O)(2)]·H(2)O}(n), seven of the nine coordination sites of the monocapped square-anti-prismatic geometry are occupied by three O atoms of the same citrate trianion (an O atom of the hy-droxy unit and the formally single-bond O atoms from two carboxyl units). Two other coordination sites are occupied by the O atoms of a chelating carboxyl unit of another citrate; one of these atoms is additionally involved in bridging. The seventh coordination site is occupied by the O atom of the formally double-bond O atom of a neighboring citrate. The remaining two coordination sites are occupied by water mol-ecules. The citrate functions in a ?(3)-bridging mode, connecting the metal atoms into a ribbon structure parallel to [010]. The structure is consolidated into a three-dimensional network by O-H?O hydrogen bonds.

Poly[[(?-3-amino-pyrazine-2-carboxyl-ato-?N,O:O')diaqua-(?-oxalato-?O,O:O,O)lanthanum(III)] monohydrate].

Project description:The water-coordinated La(III) atom in the title compound, {[La(C(5)H(4)N(3)O(2))(C(2)O(4))(H(2)O)(2)]·H(2)O}(n), is N,O-chelated by a 3-amino-pyrazine-2-carboxyl-ate ion; this ion links adjacent metal atoms to form a chain parallel to [010]. The oxalate ion serves as a bis-bidentate chelate that links adjacent metal atoms to form a chain parallel to [001]. The two bridging ions give rise to a layer motif parallel to (100) in which the La(III) atom exists in a distorted tricapped trigonal prismatic geometry. Extensive hydrogen bonding between the constituents stabilizes the structure.
