Abstract:
A compound of the general formula I[LnMmXp]zYq â€ƒâ€ƒformula I whereM is manganese in oxidation state II, III, IV and/or V, iron in oxidation state II and/or IlIl or cobalt in oxidation state II and/or III, X is a coordination group or bridging group, Y is a counterion in the corresponding stoichiometric amount to balance an existing charge z, where z as the charge of the metal complex can be positive, zero or negative, n and m, independently of one another, are integers from 1 to 4, p is an integer from 0 to 15, q is z/charge of Y, L is an organic ligand of the general formula II whereR1 and R2, independently of one another, are hydrogen, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 3 carbon atoms, an alkenyl or alkinyl group having 2 to 8 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms or a phenyl group which may also be substituted, each D, independently of one another, is NR3, O, PR3 or S, where R3 is an alkyl group having 1 to 6 carbon atoms, an alkenyl or alkinyl group having 2 to 8 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms or a phenyl group which may also be substituted, each E, independently of one another, is N, P or C(R1) with the meanings given above for R1, t is a number from 0 to 6, s is a number from 1 to 5 and u is a number from 1 to 4, A is a C3- to C9-cycloalkyl, phenyl, 1,1 â€²-biphenyl, naphthyl, anthracenyl or pyridinyl radical, each R4, independently of one another, is hydrogen, a C1- to C6-alkyl group, a C1- to C3-alkoxy group, a C3- to C1O-cycloalkyl group or a phenyl group which may also be substituted, v is a number from 0 to 15, K is a group coordinating to at least one of the metal centers M and is of the type â€”O, â€”OR, â€”S, â€”SR, â€”NR2, â€”NR, â€”PR2 or â€”PR, where R is hydrogen, an alkyl group having 1 to 6 carbon atoms, an alkenyl or alkinyl group having 2 to 8 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms or a phenyl group which may also be substituted, X is an anion of the following formulae: Fâˆ’, Clâˆ’, Brâˆ’, SCNâˆ’, OHâˆ’, O22âˆ’, O2âˆ’, R10OOâˆ’, H2O, HSâˆ’, CNâˆ’, OCNâˆ’, S2âˆ’, N3âˆ’, NH3, NR103, NR02âˆ’, R10Oâˆ’, R10COOâˆ’, R103âˆ’ and R10SO4âˆ’, where R10 is in each case hydrogen, C1- to C8-alkyl, C3- to C8-cycloalkyl or C6- to C18-aryl, and Y if z is positive, is an anion of the following formulae: Fâˆ’, Clâˆ’, Brâˆ’, NO3âˆ’, CIO4âˆ’, SCNâˆ’, PF6âˆ’, R10SO4âˆ’, R10COOâˆ’, R10SO3âˆ’, BF4âˆ’, BPh4âˆ’and SO42âˆ’ and if z is negative, is a cation of the following formulae: Li+, Na+, K+, Mg2+, Ca2+, Al3+, NH4+, R10NH3+, R102NH2+, R103NH+and R104N+, where R10 has the meaning given above.
