Abstract
In the title compound, [Zn(CH3COO)2(C28H21N3O)], the ZnII ion is in a trigonal–bipyramidal ZnN3O2 coordination with a tridentate N-chelating 4′-[4-(benzyloxy)phenyl)-2,2′:6′,2′′-terpyridine ligand in the equatorial position and two acetate anions in the axial positions. The three pyridine rings are approximately coplanar, with a maximum deviation of 0.03 Å from the mean plane. The phenoxy substituent makes a dihedral angle of 18.1 (2)° with the central pyridine ring. The benzyl group has a C—O—C—C torsion angle of 77.62 (8)° relative to the phenoxy ring. In the crystal, molecules are linked via C—H⋯O hydrogen bonds.

In the title compound, [Zn(CH3COO)2(C28H21N3O)], the ZnII ion is in a trigonal–bipyramidal ZnN3O2 coordination with a tridentate N-chelating 40 -[4-(benzyloxy)phenyl)-2,20 :60,200 terpyridine ligand in the equatorial position and two acetate anions in the axial positions
Molecules are linked via C—H O hydrogen bonds
Functionalized terpyridines are interesting materials (Heller & Schubert, 2003). 2,2′:6′,2"-terpyridine and its derivatives have been used as key building blocks in supramolecular frameworks (Duprez et al, 2005)
