title: 2-[4-(Dimethyl-amino)phen-yl]imidazo[4,5-f][1,10]phenanthroline sesquihydrate.
abstract: There are two formula units in the asymmetric unit of the title compound, C(21)H(17)N(5)·1.5H(2)O. The imidazo[4,5-f][1,10]phen-an-throline unit is almost coplanar with the benzene ring, the dihedral angles between them being 8.91 (5) and 4.93 (6)° in the two mol-ecules. The crystal structure is stabilized by a series of hydrogen bonds between the water mol-ecules and the N atoms of the imidazophenanthroline groups.
