Poly[aqua-[?(5)-5-(isonicotinamido)-isophthalato][?(4)-5-(isonicotinamido)-isophthalato]cerium(III)silver(I)].

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 ?-? inter-actions between the pyridine and benzene rings [centroid-centroid distances = 3.642?(4) and 3.624?(3)?Å] stabilize the crystal structure.

Project description:The title complex, [Dy(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a dysprosium coordination polymer with mixed anions and was obtained under hydrothermal conditions. In the structure, the oxalate and 5-amino-isophthalate ligands link the dysprosium ions, building up a two-dimensional metal-organic framework parallel to the (10) plane. These sheets are further connected through O-H?O, N-H?O and C-H?O hydrogen bonds, forming a three-dimensional supra-molecular structure.

catena-Poly[[aqua-(2,2'-bipyridyl)cobalt(II)]-μ-5-nitro-isophthalato].

Project description:In the crystal structure of the title compound, [Co(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co(II) ion, one O-monodentate 5-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.

Poly[[diaqua-hexa-?-cyanido-cerium(III)ferrate(III)] dihydrate].

Project description:In the structure of the title complex, {[CeFe(CN)(6)(H(2)O)(2)]·2H(2)O}(n), the Ce(III) and Fe(III) atoms exhibit square anti-prismatic [CeN(6)(H(2)O)(2)] (site symmetry m2m) and octahedral [FeC(6)] (site symmetry 2/m) coordination geometries, respectively. The metal atoms are linked alternately through the cyanide groups, forming a three-dimensional framework in which the {Ce(2)Fe(2)(CN)(4)} puckered square unit is the basic building block. The crystal packing is enforced by O-H?O and O-H?N hydrogen bonds, including the uncoordinated water molecule which is located on a mirror plane.
