While (Ph2 CN2 )B(C6 F5 )3 is unstable, single electrontransfer from Cp*2 Co affords the isolation of stable products [Cp*2 Co][Ph2 CNNHB(C6 F5 )3 ] 1 and [Cp*Co(C5 Me4 CH2 B(C6 F5 )3 )] 2. The analogous combination of Ph2 CN2 and BPh3 showed no evidence of adduct formation and yet single electrontransfer from Cp*2 Cr affords the species [Cp*2 Cr][PhC(C6 H4 )NNBPh3 ] 3 and [Cp*2 Cr][Ph2 CNNHBPh3 ] 4

characterized. The increase of nuclearity of clusters under reduction was shown. Fe3(CO)12 preserves the Fe3 core under reduction forming the [Fe3(CO)11]2– dianions in 7. The [CpMo(CO)3]2 and [Mn(CO)5]2 dimers dissociate under reduction forming mononuclear [CpMo(CO)3]– (8) and [Mn(CO)5]– (9) anions. In all anions the increase of negative charge on metal atoms shifts the bands attributed to carbonyl C–O

Reduction of 5,10,15-triphenylcorrole (H3TPCor) with decamethylchromocene yields (Cp*2Cr+)(H+)(H2TPCor•2-).C6H4Cl2 (1). It is accompanied by deprotonation of H3TPCor and the formation of planar radical H2Cor(.2-) dianions. Complex 1 manifests a band at about 750 nm observed in solution spectra of H2TArylCor(.2-) and demonstrates an EPR signal attributed to the reduced corrole macrocycle. Magnetic moment

Pc˙3− macrocycles. These macrocycles form closely packed double stacks in 1 with effective π–π interactions providing strong antiferromagnetic coupling of spins at a Weiss temperature of −80 K. Decamethylchromocene initially also reduces SnIVCl2(Pc2−) to form the [(Cp*2Cr+)SnVICl2(Pc˙3−)}˙− complex but further reaction between the ions is observed. This reaction is accompanied by the substitution of
