- <p>This paper investigates the reactivity and optical properties of transition metal-incorporated organoantimony(<br>V) clusters prepared by a solvothermal route. The detailed structural characterization of novel heterometallic<br>M2Sb4 oxo clusters is reported herein. Single crystal X-ray diffraction revealed the formation<br>of hexanuclear organoantimony(V) based oxo clusters [(p-ClC6H4Sb)4V2(O)2(μ3-O)2(μ2-O)2(t-BuPO3)4(μ2-<br>OCH3)4] (1), [M2(p-iPr-C6H4Sb)4(μ3-O)2(μ2-O)2(μ2-OCH3)4(t-BuPO3)4(py)2]·xCH3OH, where M = Mn, x =<br>2 (2), Co, x = 1 (3), Ni, x = 2 (4) and Cu, x = 2 (5). The magnetic behaviour of the clusters was probed by<br>magnetic susceptibility measurements. Optical absorption studies showed that bandgap reduction can be<br>achieved by incorporating an appropriate transition metal into the homometallic Sb6 oxo cluster.</p>
