Manganese catalysed reduction of dioxygen to hydrogen peroxide: structural studies on a manganese(III)–catecholate complex

Autor: Pamela Carr, Tippu S. Sheriff, Brian Piggott

Publikováno v: Inorganica Chimica Acta. 348:115-122

The complex [Na]5[Mn(3,5-(SO3)2Cat)2]·10H2O (H2Cat=1,2-dihydroxybenzene) has been synthesised and characterised by X-ray diffraction (triclinic system, space group P 1 ). The characterisation of this complex supports previous work that manganese(III

Synthesis and X-ray crystallographic structure of Ga4(OH)6(3-ButpzH)10I6·2MeCN: a quasi double heterocubane

Autor: Brian Piggott, Paul Hodge

Publikováno v: Chemical Communications. :1933-1934

The reaction of K[HB(3-Butpz)3] with GaI3 resulted in breakdown of the ligand and formation of a novel Ga/O cluster. This compound can be described as four edge-sharing Ga/O,N octahedra or as two face sharing partial Ga/O heterocubanes, i.e. a quasi
