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

ABSTRACT: In the hydro-thermally synthesized title compound, [Ce(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the Ce(III) ion is coordinated by four O atoms from two different oxalate ligands, three O atoms from two symmetry-related pyrazine-2-carboxyl-ate ligands, two O atoms from two water melecules and one N atom from a pyrazine-2-carboxyl-ate ligand in a distorted bicapped square-anti-prismatic coordination geometry. The oxalate and pyrazine-2-carboxyl-ate ligands bridge the Ce(III) ions, forming a two-dimensional structure. In addition, inter-molecular O-H?O and O-H?N hydrogen bonds connect the two-dimensional structure into a three-dimensional network.

Project description:In the title complex, [La(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by one N and three O atoms from two pyrazine-2-carboxylate ligands, by four O atoms from two oxalate ligands and by two O atoms of two water molecules, displaying a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups of pyrazine-2-carboxyl-ate and oxalate ligands link the lanthanum metal centres, forming layers parallel to (10). The layers are further connected by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network.

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.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

The two crystallographically independent oxalate ligands, each lying on an inversion center, act as bridging ligands, linking Nd atoms into an extended zigzag chain. Neighboring chains are linked by the pyrazine-2-carboxyl-ate ligands into a two-dimensional layerlike network in the (10) plane. The layers are further connected by O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional supra-molecular network.

The oxalate anions link neighbouring neodymium(III) metal centres into Nd-oxalate chains, which are inter-connected by Ag(2-pyz)(2) units, forming a three-dimensional polymeric framework. Inter-molecular O-H?O and C-H?O hydrogen bonds are observed in the crystal structure.
