- Аннотация: Reactions of InIIIClPc or TlIIIClPc phthalocyanines with monodeprotonated tetraphenylporphyrin HTPP−− anions have been studied under reduction or in the presence of NN-methylimidazole (NN-MeIm). Formation of salt {InIII(N(N-MeIm)2(TPP2−)2−)}++{InIII(Pc2−)22−)2}−−⋅4C6H4Cl2 (1) justifies partial abstraction of indium(III) atoms from InIIIClPc to form cationic {InIII(TPP2−)2−)}++ porphyrinssolvated by NN-MeIm and double-decker {InIII(Pc2−)22−)2}−− anions. Crystals of TlI(HTPP−)−) (2) have been only obtained at the interaction of HTPP−− with TlIIIClPc under reduction indicating that TlIII is reduced to TlI and is abstracted by HTPP−−. To confirm the possibility of TlI formation under reduction we have studied reduction of TlIIIClPc by sodium fluorenone in the presence of cryptand[2.2.2]. Crystals of {Cryptand(Na+)+)}(TlI(Pc2−)2−)}−−⋅C6H4Cl22 (3) have been isolated indicating metal-centered reduction of TlIIIClPc to form TlI and preserving dianionic Pc2−2− macrocycles. Optical spectra and structures of the obtained compounds are discussed and compared with those of pristine MIIIClPc. It is shown that 1– 3 are EPR silent due to the formation of diamagnetic components.
