2-acetato-aquadi-3-isonicotinato-holmium(III)silver(I)] perchlorate]Abstract: In the title three-dimensional heterometallic complex, {[AgHo(C6H4NO2)2(C2H3O2)(H2O)]ClO4}n, the HoIII 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 molecule. The two-coordinate AgI 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 molecules link the carboxylate 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).
