Artemenko, M. V. published the artcileComplex formation in the cupric nitrate-1-methyl-2-(hydroxymethyl)benzimidazole-methanol system, Synthetic Route of 7467-35-8, the publication is Zhurnal Neorganicheskoi Khimii (1967), 12(11), 3055-61, database is CAplus.
The complex formation of Cu(NO3)2 with 1-methyl-2-(hydroxymethyl)benzimidazole (I) in MeOH was studied by means of various optical methods. Four complex compounds, 2 addition products with the molar ratio of Cu:I = 1:1 and 1:3 and the other 2 mixed chelate alcoholates with 1:1 and 1:2 composition, were found. On the basis of the anal. the absorption spectra of the isomolar series of the solutions were decomposed into sep. Gaussian components. The application of crystal field theory established that these complex compounds have a tetragonal bipyramidal configuration. The optical characteristics for the detected bands of these complex compounds are given. The Me group in the 1 position in the I mol. has no influence on the composition and optical characteristics of the complex compounds
