Tunable bandgaps in self-assembled transition metal-incorporated heterometallic MSb (M = V, Mn, Co, Ni, and Cu) oxo clusters.

This paper investigates the reactivity and optical properties of transition metal-incorporated organoantimony(V) clusters prepared by a solvothermal route. The detailed structural characterization of novel heterometallic MSb oxo clusters is reported herein. Single crystal X-ray diffraction revealed the formation of hexanuclear organoantimony(V) based oxo clusters [(-ClCHSb)V(O)(μ-O)(μ-O)(-BuPO)(μ-OCH)] (1), [M(-iPr-CHSb)(μ-O)(μ-O)(μ-OCH)(-BuPO)(py)]·CHOH, where M = Mn, = 2 (2), Co, = 1 (3), Ni, = 2 (4) and Cu, = 2 (5).

Discrete Molecular Aggregates Based on Zn and Sb Ions Displaying Efficient Antibacterial and Antioxidant Properties.

The reactions of [ZnCl(3,5-MePzH)(-BuPO)] with organostibonic acid in varying reaction conditions have been investigated. Single-crystal X-ray diffraction studies reveal the formation of [Zn(-ClCHSb)(O)(OCH)(-BuPO)(py)] (), [Zn(-ClCHSb)(Sb)(O)(-BuPOH)(-BuPO)(py)Cl] (), and [Zn(RSb)(O)(OCH)(-BuPO)(py)], where R = -ClCH () and R = -iPrCH (), respectively. Interestingly, in the synthesis of , complete dearylation of organoantimony moieties followed by C-F bond formation, a reduction from Sb (V) to Sb (III), and Sb···Cl weak intermolecular interactions have been observed.

Bismuth and Titanium Phosphinates: Isolation of Tetra-, Hexa- and Octanuclear Clusters.

The reaction of organobismuth precursors with trityl--phosphinic acid in varying reaction conditions afforded colorless crystals, whose single crystal X-ray characterization revealed the formation of monomer {(PhBi)[(PhC)(H)PO]}·/(CHCN)./HO () and butterfly shaped tetranuclear cluster Bi(μ-O)[(PhC)(H)(PO)]·2CHCl·/CHCN.2HO ().
