title: Poly[[μ(2)-acetato-aquadi-μ(3)-isonicotinato-holmium(III)silver(I)] perchlorate].
abstract: In the title three-dimensional heterometallic complex, {[AgHo(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the Ho(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from 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 from two different isonicotinate anions. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. The coordinated water mol-ecules link the carboxyl-ate group of the acetate ligand and the nitrate ligand by O-H⋯O hydrogen bonding. The crystal structure is further stabilized by hydrogen bonds. The perchlorate ion is disordered over two sites with site-occupancy factors 0.539 (12) and 0.461 (12), while the methyl group of the acetate ligand is disordered over two sites with site-occupancy factors 0.51 (4) and 0.49 (4).
