The isolation, separation, and chemistry of dithio- and perthioaryl-carboxylate complexes of Ni(II), Pd(II), and Pt(II) were reported in two complementary reports (381, 415). The perthiocarboxylate complexes have also been obtained by oxidative addition of sulfur to the dithiocar-boxylic acid complexes. The abstraction of the sulfur atom adjacent to carbon by PPha was again observed, and rationalized as follows.

The chemistry of manganese(III) with monodentate carboxylates, such as acetate and benzoate or their derivatives, results in the formation of complexes with nuclearities of 2, 3, 4, 6, 7, 8, 9, 10, and 18. The chemistry of polynuclear carboxylate complexes is too extensive to detail here and coverage is confined to a brief discussion of the structural types involved. 

Carboxylate anions are versatile ligands that are found in a variety of coordination modes including unidentate, chelate, and a number of bis(monodentate) bridging modes.1 Such versatility makes the chemistry of carboxylate complexes particularly interesting. It is now also apparent that the diverse catalytic activity shown by many metal carboxylates may be rationalized in terms of the chemistry of the carboxylato ligand.2 In general though, few rational syntheses of metal carboxylates are known.1 This... 

Structurally characterized trivalent manganese imidazole or imid-azolate complexes are also extremely rare. Current examples are limited to Mn(III) porphyrins (61), Mn(III) thiolates (Section III,B)> a Mn(III) salicylate complex (Section IV,B) and Mn(III) and Mn(IV) carboxylate complexes (Section VI,B) (62). None of these complexes contains a Mn-to-imidazole ratio greater than two consequently, no structural model for Mn SOD exists presently in Mn coordination chemistry. However, a five-coordinate Mn(II) monomer with three imidazole ligands, Mn(2-Me-ImH)3Cl2 (ImH = imidazole), has been characterized by X-ray diffraction techniques (63). 

In a review of the stereochemistry of a-hydroxycarboxylate complexes, Tapscott includes the structural chemistry of complexes that contain ligands in which a sulfur atom is attached to a carbon a to a carboxylic group. This includes both a-mercapto and a-thioether groups. Lists of structural bonding parameters for a-thiocarboxylate complexes are given together with parameters for chelate rings.
