A similarity in the visible spectra of some /i-oxo-di-/i-acetato Mn(III) dinuclear complexes to the spectrum of Mn catalase has been noted (168-174). Reaction of hydrotris(l-pyrazolyl)borate, [HB(pz)3], or 1,4,7-triazacyclononane (TACN) with Mn(0Ac)3 2H20 results in the formation of the dinuclear complexes [Mn2in0(0Ac)2(HB(pz)3)2] (168) and [Mn/1 0(0Ac)2(TACN)2]2+ (169). Selected structural parameters are given in Table VII. The dimanganese cores of the complexes are essentially identical to those of some /i-oxo-di-/i-carboxylato diiron(III) complexes (177,178), which have been shown to be excellent structural models of the diiron site in methemerythrin (Fig. 8) (179). 

Unsubstituted tris(pyrazolyl)borate has been used to stabilize trimethyl, dimethylhydrido, dimethyl(hydroxido), dimethyl(carboxylato), and dimethylthiolato complexes 983-9857 The dimethyl(hydrido)platinum(iv) complex 986 was characterized by comparison of the NMR data with the above-related complexes, and theoretical calculations of a tris(iminoamino)borate complex provided reasonable results for the Pt(iv) complex with a hydride ligand 987 rather than a potential Pt(ii) hydrogen-bonded species 9887 ...
