Abstract
A bis-bidentate bridging ligand H2L with inequivalent hard and
soft binding sites (catecholate and pyrazolyl-pyridine, respectively)
reacts with a mixture of Ti(IV) and Zn(II) ions to afford an
octanuclear heterometallic Ti4Zn4 cyclic helicate formed from four
dinuclear {TiZn(m-L)2} units connected in a ring via methoxide ions.
