- Аннотация: Reactions of InIIIClPc or TlIIIClPc phthalocyanines with monodeprotonated tetraphenylporphyrin HTPP− anions have been studied under reduction or in the presence of N-methylimidazole (N-MeIm). Formation of salt {InIII(N-MeIm)2(TPP2−)}+{InIII(Pc2−)2}−⋅4C6H4Cl2 (1) justifies partial abstraction of indium(III) atoms from InIIIClPc to form cationic {InIII(TPP2−)}+ porphyrinssolvated by N-MeIm and double-decker {InIII(Pc2−)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−)}−⋅C6H4Cl2 (3) have been isolated indicating metal-centered reduction of TlIIIClPc to form TlI and preserving dianionic Pc2− 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.
