Zwitterionic form of tris-({[5-(4-meth-oxy-phenyl-azo)salicyl-idene]amino}-eth-yl)amine.

ABSTRACT: THE TITLE COMPOUND (SYSTEMATIC NAME:2-{[2-(bis-{2-[({2-hy-droxy-5-[(4-meth-oxy-phen-yl)diazen-yl]phen-yl}methyl-idene)amino]-eth-yl}amino)-eth-yl]aza-niumylidenemeth-yl}-4-[(4-meth-oxy-phen-yl)diazen-yl]phenolate), C(48)H(48)N(10)O(6), exists as a zwitterion in the solid state. The three arms of the tripodal mol-ecule are located close to each other and an intra-molecular hydrogen bond occurs in each arm (O-H?N in two arms and N-H?O in the zwitterionic arm). The dihedral angles between the aromatic rings in the three arms are 16.36?(14), 23.94?(14) and, for the zwitterionic arm, 37.14?(14)°. In the crystal, a weak inter-moleclar N-H?O hydrogen bond occurs.
