چکیده
In the title coordination polymer, [La(C(5)HN(2)O(4))(H(2)O)(2)](n), the lanthanum(III) metal centre is nine-coordinated, with a distorted tricapped trigonal prismatic geometry, by the O atoms of two water mol-ecules and by two N and five O atoms of two N,O-bidentate, one O,O'-bidentate and one O-mono-dentate 3,5-dicarb-oxyl-ato-pyra-zol-1-ide ligands. The polymeric three-dimensional structure is stabilized by inter-molecular O-H⋯O hydrogen bonds.

In the title compound, [Ce(C(9)H(4)N(2)O(4))(C(2)H(3)O(2))(H(2)O)](n), the Ce(III) ion is coordinated by five O atoms and one N atom from four 1H-benzimidazole-5,6-dicarboxyl-ato (L) ligands and by two O atoms from an acetate ligand and one aqua ligand, forming a slightly distorted tricapped trigonal-prismatic geometry. The L ligands are bridging, forming a layered polymer parallel to (010). In...

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 l...
