Mixed N,S tripodal ligands bis(2,4-dimethylphenylthioethyl)(2-methylbenzimidazolyl)amine L 1 , bis(2,4-dimethylphenylthioethyl)(1-methyl-2-methylbenzimidazolyl)amine L 2 , and bis(1-methyl-2-methylbenzimidazolyl)(2-methylthioethyl)amine L 3 were employed to prepare the corresponding copper complexes. L 1 and L 2 associate weakly with Cu 2+ , while the...
p-tert-Butylcalix[4]arene [C4(OH) 4 ] was substituted with one to four benzimidazole groups at the phenolic positions affording the compounds C4(OH) 3 (OBzIm)–C4(OBzIm) 4 . The solid-state structures confirmed the cone conformation of all derivatives. A tetrasubstituted calix[4]arene with two benzimidazole groups and two 4-methylenestyryl in distal positions C4(OStyr) 2...
