Poly[[?(2)-acetato-aquadi-?(3)-isonicotinato-erbium(III)silver(I)] perchlorate].

ABSTRACT: In the title three-dimensional heterometallic complex, {[AgEr(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the eight-coordin-ate Er(III) ion adopts a distorted bicapped trigonal-prismatic geometry, being coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of the water mol-ecule. The two-coordinate Ag(I) ion is surrounded by two N atoms from two different isonicotinate anions in a slightly bent configuration. These building blocks are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. Ths structure is consolidated by O-H?O hydrogen bonding between the coordinated water mol-ecule and a carboxyl-ate group of the acetate ligand. The perchlorate anion is disordered over two sites with site-occupancy factors of 0.526?(13) and 0.474?(13), while the methyl group of the acetate ligand is equally disordered over two sites.

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.

Poly[[tetra-kis-(μ(2)-pyrazine N,N'-dioxide-κO:O')erbium(III)] tris-(perchlorate)].

Project description:The title three-dimensional coordination network, {[Er(C(4)H(4)N(2)O(2))(4)](ClO(4))(3)}(n), is isostructural to that of other lanthanides. The Er(+3 )cation lies on a fourfold roto-inversion axis. It is coordinated in a distorted square-anti-prismatic fashion by eight O atoms from bridging pyrazine N,N'-dioxide ligands. There are two unique pyrazine N,N'-dioxide ligands. One ring is located around an inversion center, and there is a a twofold rotation axis at the center of the other ring. There are also two unique perchlorate anions. One is centered on a twofold rotation axis and the other on a fourfold roto-inversion axis. The perchlorate anions are located in channels that run perpendicular to (001) and (110) and inter-act with the coordination network through C-H⋯O hydrogen bonds.

catena-Poly[[silver(I)-μ-dipyrazin-2-ylamine] perchlorate monohydrate].

Project description:In the title complex, {[Ag(C(8)H(7)N(5))]ClO(4)·H(2)O}(n), the multidentate dipyrazin-2-ylamine acts as a μ(2)-bridging link with an anti-syn configuration, assembling the Ag(I) ions into a zigzag chain structure. The Ag(I) ion is linearly coordinated by two dipyrazin-2-ylamine ligands through two pyrazine N atoms. (ClO(4) (-))⋯π(pyrazine) [O⋯centroid distances of 3.612 (3) and 3.664 (1) Å] and π-π inter-actions [centroid-centroid distance = 3.518 (2) Å] as well as O-H⋯O and N-H⋯O hydrogen-bonds assemble the chains into a three-dimensional supra-molecular aggregation.

catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-?O)bis-(nitrato-?(2) O,O')erbium(III)] [silver(I)-di-?-sulfido-tungstate(VI)-di-?-sulfido]].

Project description:In the title compound, {[Er(NO3)2(C6H18N3OP)4][AgWS4]} n , the polymeric anionic chain {[AgWS4](-)} n extends along [001]. The Er(III) atom in the cation is coordinated by eight O atoms from two bidentate nitrate anions and four hexa-methyl-phospho-ramide ligands in a distorted square-anti-prismatic geometry. Together with the two nitrate ligands, the cation is monovalent, which leads to the anionic chain having a [WS4Ag] repeat unit. The polymeric anionic chain has a distorted linear configuration, with W-Ag-W and Ag-W-Ag angles of 161.37?(2) and 153.548?(12)°, respectively. The title complex is isotypic with the Y, Yb, Eu, Nd, La, Dy, Sm, Lu and Tb analogues.

catena-Poly[[silver(I)-μ-4-aminopyridine] perchlorate]: a 1-D staircase coordination polymer.

Project description:Reaction of 4-amino-pyridine with silver(I) perchlorate leads to a one-dimensional coordination polymer, {[Ag(C(5)H(6)N(2))]ClO(4)}(n), in which the amino-pyridine binds through both N atoms. The perchlorate anion is hydrogen bonded to the amino H atoms and inter-acts weakly with the silver(I) atoms (Ag-O > 2.70 Å), both located on inversion centres, and some aromatic H atoms (O-H > 2.55 ÅA), thereby extending the dimensionality of the assembly. This is the first silver complex in which this ligand acts in a bridging mode.

The coordination numbers of the two La ions are 9 and 10. Adjacent layers of the structure, which extend parallel to (100), are linked by O-H?O hydrogen bonds and are also held together by van der Waals inter-actions between the CH(3) groups of the acetate anions.
