Poly[[diaqua-[?(2)-3-carb-oxy-5-(pyridine-4-carboxamido)-benzoato][?(4)-5-(pyridine-4-carboxamido)-isophthalato]cerium(III)] monohydrate].

ABSTRACT: In the title compound, {[Ce(C(14)H(9)N(2)O(5))(C(14)H(8)N(2)O(5))(H(2)O)(2)]·H(2)O}(n), three carboxyl groups of two independent isophthalate anions are deprotonated and they bridge the Ce(III) cations, forming a two-dimensional polymeric structure parallel to (001); another carboxyl group is not deprotonated and links with the adjacent pyridine ring via an O-H?N hydrogen bond. The Ce(III) cation is coordinated by six O atoms from carboxyl groups and two O atoms from coordinated water mol-ecules in a distorted square-anti-prismatic arrangement. Extensive O-H?O and O-H?N hydrogen bonding occurs in the crystal structure.

Project description:The Zn(II) atom in the title polymeric compound, {[Zn(C(8)H(6)NO(4))(2)(H(2)O)(2)]·2H(2)O}(n), lies on a center of inversion and is coordinated by two amine N atoms and two carboxyl-ate O atoms from two 3-amino-5-carb-oxy-benzoate anions along with two water mol-ecules in a distorted octa-hedral geometry.

One H atom of the coordinated water mol-ecule and one H atom of the solvent water mol-ecule are each disordered over two positions in a 1:1 ratio.
