Synthesis, X-ray structures and characterization of beryllium phthalocyanine and (2-ethoxyethanol)-aqua-beryllium phthalocyanine
摘要:
Crystals of beryllium phthalocyanine (1) were obtained from the reaction of beryllium pieces with 1.2-dicyanobeilzene at 270 degrees C. In subsequent preparatory work the beryllium phtholocyanine was transformed into the monoaxially ligated compound (2-ethoxyethanol)aqua-beryllium phthalocyanine (11). The crystal structures of (1) and (11) were determined by single crystal X-ray diffraction. Based on thermogravimetric measurements, a conversion of the beryllium phthalocyanine into beryllium plithalocyanine monohydrate in wet air has been followed in detail. The beryllium phthalocyanine monohydrate and compound 11 loose the ligated water and 2-ethoxyethanol in the 150 degrees C region. The EPR spectra of the beryllium phthalocyanine complexes as exposed to air have been recorded and discussed. (c) 2005 Elsevier B.V. All rights reserved.
