1,2-Maleonitrile 1,2-dithiolate ligands ligand structures

Three 1 1 Fe Cu model compounds have been reported, each of which contains a dmuclear anion in which an iron(III) porphyrin and a copper(II) maleonitrile dithiolate are bridged by one of the thiolate anions. The other ligand to Fe in each case is THF. The cations of the three compounds are either [TPPFe(THF)2]+, [TPPGa(THF)2]+, or [TPPA1(THF)(H20)]+ (Figure 8(e)). The structural results and the Mossbauer parameters suggest that the Fe center in... 

The structures of typical ligands were shown earlier in Figure 1.9 and will also be shown later in Figures 3.1 and 3.2. Complexes include some metal halides, hydrates, amines, amides and imides, such as Ti(NR2)4 (R is an alkyl group), oxides, H3B NR3 (a borane-amine adduct), Co(MNT)2 (MNT = maleonitrile dithiolate), Cupc (pc = phthalocyanine), Mo(CO)6, cluster carbonyls, and metal acetylacetonate derivatives. 

For platinum(II), Balch and coworkers [78] have studied the reaction of a biscar-bene platinum(II) dicyanide complex with thallium(I) in basic solution (Scheme 18). They obtained two polymorphs involving Pt -Xl contacts a yellow dimeric structure and a red extended structure. Subsequent work by the same authors [79] showed that replacement of the CN ligands with dimethylglyoxime or maleonitrile dithiolate provides access to a range of extended structures based on Pt i Xl interactions.
