Synthesis and structure of di-mu-iodo-bis(phthalocyaninato)bismuth(III)

A new phthalocyanine dinuclear complex of bismuth, di-mu-iodo-bis(phthalocy aninato)bismuth(III) has been obtained by the reaction of Bi2Se8 and 1,2-di cyanobenzene under iodine vapour. The crystal structure of the complex was determined by X-ray diffraction method. The dinuclear complex is centrosymm etric with two dependent symmetrically BiPcI (Pc = C32H16NS32-) units. The bismuth atom is coordinated by four isoindole nitrogen atoms and two bridge d iodine atoms. The formation and structural features of (BiPcI)(2) are rel ated to other iodo-phthalocyaninato-bismuth(III) complexes from literature.
