Mixed-organo

Mixed organo antimony ligands with one or two electronegative groups have been only rarely used in transition metal chemistry. The resulting complexes belong to type 3 or 4 with -Sb coordination (Scheme 2). 

Mixed organo(dihalo)tellurates(II) are obtained when the halides in the starting materials are different. 

D. Mixed-Organo(arenethiolato)copper and Mixed-Arenethiolatocopper Copper Halide Aggregates... 

The structures of copper(I) thiolates in which the only other donor functions present are those of the auxiliary ligands (Table III) often resemble structures of those species in which the arenethiolate ligands have a heteroatom containing function that can coordinate intramolecularly to the metal center (Table IV). There are some structurally characterized mixed-organo(arenethiolato)copper(I) and arenethiolatocopper copper halide aggregates in which intramolecular coordination is present. These aggregates are collected in Table V, which allows some direct comparisons to be made between the two types of species. For ease... 

Mixed-Organo(arenethiolato)copper(I) and Arenethiolatocopper Copper Halide Species... 

Besides the pure copper thiolate aggregates [Cu(SR)] , there are several reported examples of mixed-organo(arenethiolato)copper(I) aggregates in which... 

It is important to note that all known examples of mixed-organo-(arenethiolato)copper(I) aggregates possess additional coordination from a donor substituent. A typical example is trinuclear [Cu3 SC6H3(CH2NMe2)-2-Cl-...

Redistribution may occur between two R2Be compounds to form a mixed organo-metallic ... 

The alkoxides can be arranged in four general groups homoleptic alkoxides of the Ln(OR)3 type, mixed organo/alkoxides RxLn(OR )3.x, halide/alkoxides Ln(OR)xHal3 j and similar compounds including oxo/alkoxides and bimetallic complexes Ln[M(OR)j3.
