Catena-Poly[[[tetra-aqua-samarium(III)]-di-μ-isonicotinato-κO:O'] chloride].

ABSTRACT: In the structure of the title compound, {[Sm(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the unique Sm(III) atom lies on a crystallographic twofold axis and is eight-coordinated by four O atoms from four isonicotinate ligands and four water mol-ecules in a slightly distorted square-anti-prismatic coodination environment. The Sm(III) atoms are bridged by two carboxyl-ate groups of two isonicotinate ligands, forming an extended chain along the c-axis direction. These chains are cross-linked through hydrogen bonds, forming a three-dimensional framework, with channels which accommodate the chloride anions.

Project description:The title compound, [CuEu(2)(C(6)H(4)NO(2))(8)(H(2)O)(4)](n), displays a one-dimensional chain structure. The four-coordinate Cu(II) ion (site symmetry ) adopts a trans-CuN(2)O(2) geometry and is bridged by two carboxyl-ate groups from two isonicotinate ligands. The Eu(III) ion adopts a distorted square-anti-prismatic geometry, being coordinated by four O atoms from bridging carboxyl-ate groups of four isonicotinate ligands, two O atoms from chelating carboxyl-ate groups of one isonicotinate ligand and two O atoms from coordinated water mol-ecules; adjacent Eu(III) ions in the chain are related by inversion. The water mol-ecules interact with the ligands via O-H⋯N hydrogen bonds [O⋯O = 2.782 (3)-2.881 (3) Å], which link the chains into a three-dimensional structure.

Poly[[(μ(2)-acetato-κO,O':O')aqua-bis-(μ(3)-isonicotinato-κO:O':N)samarium(III)silver(I)] perchlorate].

Project description:The title compound, {[AgSm(C(6)H(4)NO(2))(2)(CH(3)CO(2))(H(2)O)]ClO(4)}(n), is a three-dimensional heterobimetallic complex constructed from a repeating dimeric unit. Only half of the dimeric moiety is found in the asymmetric unit; the unit cell is completed by crystallographic inversion symmetry. The Sm(III) ion is eight-coordinated by four O atoms of four different isonicotinate ligands, three O atoms of two different acetate ligands, and one O atom of a water mol-ecule. The two-coordinate Ag(I) ion is bonded to two N atoms of two different isonicotinate anions, thereby connecting the disamarium units. In addition, the isonicotinate ligands also act as bridging ligands, generating a three-dimensional network. The coordinated water mol-ecules link the carboxyl-ate group and acetate ligands by O-H⋯O hydrogen bonding. Another O-H⋯O hydrogen bond is observed in the crystal structure. The perchlorate ion is disordered over two sites with site-occupancy factors of 0.560 (11) and 0.440 (11), whereas the methyl group of the acetate ligand is disordered over two sites with site-occupancy factors of 0.53 (5) and 0.47 (5).

catena-Poly[potassium-di-μ-aqua-μ-4-(5-tetra-zolio)pyridine].

Project description:The title compound, [K(C(6)H(4)N(5))(H(2)O)(2)](n), was synthesized by hydro-thermal reaction of KOH with 4-(5-tetra-zolio)pyridine. The K atom has a distorted octa-hedral coordination environment and is coordinated by two axial N atoms from the organic ligand and by four water mol-ecules in the equatorial plane. The mol-ecules as a whole are located on crystallographic mirror planes; the K atom is also located on an inversion center. Both the water mol-ecules and the organic ligands act as bridges to link symmetrically the adjacent K atoms into polymeric chains parallel to the c axis. O-H⋯N hydrogen bonds involving the water O atoms and aromatic π-π inter-actions [centroid-centroid distance 3.80 (2) Å] between the pyridine and tetra-zole rings build up an infinite three-dimensional network.
