ABSTRACT: The title heteronuclear complex, {[AgHo(C(14)H(8)N(2)O(5))(2)(H(2)O)]·2H(2)O}(n), has a three-dimensional polymeric structure, generated by the carboxyl-ate and pyridine groups of the 5-(isonicotinamido)-isophthalate (INAIP) ligands bridging the metal atoms. The Ho(III) atom is coordinated by seven O atoms from INAIP ligands and a water mol-ecule in a distorted square-anti-prismatic geometry, while the Ag(I) atom has a distorted trigonal-planar AgN(2)O geometry. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds stabilize the crystal structure.

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.

ABSTRACT: In the title compound, [Zn(C(8)H(6)ClNO(4)S)(C(10)H(8)N(2))(H(2)O)], the Zn(II) atom is six-coordinated by two O atoms and one N atom from a tridentate Schiff base ligand and two N atoms from a chelating 2,2'-bipyridine ligand and one water mol-ecule, forming a slightly distorted octa-hedral geometry. In the crystal, O-H⋯O hydrogen bonds link pairs of complex mol-ecules into dimers. An intra-molecular O-H⋯O hydrogen bond is also present.

ABSTRACT: In the centrosymmetric polymeric title compound, {[CoHo(2)(C(14)H(8)N(2)O(5))(4)(H(2)O)(4)]·4H(2)O}(n), the Ho(III) ion is coordinated by one water mol-ecule and four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands in a distorted square-anti-prismatic arrangement. The Co(II) ion, located on an inversion center, is coordinated by two pyridine N atoms, two carboxyl-ate O atoms and two water mol-ecules in a distorted octa-hedral geometry. One L ligand bridges two Ho ions and one Co ion through two carboxyl-ate groups and one pyridine N atom. The other L ligand bridges two Ho ions and one Co ion through two carboxyl-ate groups, while the uncoordinated pyridine N atom accepts a hydrogen bond from an adjacent coordinated water mol-ecule. Extensive O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonding is present in the crystal.

ABSTRACT: The 4d-4f heteronuclear title complex, [AgCe(C(14)H(8)N(2)O(5))(2)(H(2)O)](n), has a three-dimensional framework structure, generated by the carboxyl-ate and pyridyl groups of the 5-(isonicotinamido)-isophthalate (INAIP) ligands bridging the metal ions. The Ce(III) atom is coordinated by eight O atoms from six INAIP ligands and a water mol-ecule in a distorted tricapped trigonal-prismatic geometry, while the Ag(I) atom has a distorted trigonal-planar AgN(2)O geometry. O-H⋯O and N-H⋯O hydrogen bonds and π-π inter-actions between the pyridine and benzene rings [centroid-centroid distances = 3.642 (4) and 3.624 (3) Å] stabilize the crystal structure.
