Poly[?(3)-acetato-di-?(3)-isonicotinato-?(2)-isonicotinato-samarium(III)silver(I)].

ABSTRACT: In the title homochiral three-dimensional heterometallic complex, [AgSm(C(6)H(4)NO(2))(3)(C(2)H(3)O(2))](n), the eight-coordinate Sm(III) ion displays a bicapped trigonal-prismatic geometry, being coordinated by two O atoms from one acetate ligand, four O atoms from four bridging isonicotinate ligands and two O atoms from two terminal isonicotinate ligands. The four-coordinate Ag(I) ion adopts a tetra-hedral geometry, being bonded to two N atoms from two bridging isonicotinate ligands and two O atoms from two acetate ligands. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network.

Poly[[(?(2)-acetato-?O,O':O')aqua-bis-(?(3)-isonicotinato-?O: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).

These chains are cross-linked through hydrogen bonds, forming a three-dimensional framework, with channels which accommodate the chloride anions.
