title: Bis[bis(pyrimidin-2-yl-kappaN)amine](dicyanamido-kappaN1)(trifluoromethanesulfonato-kappaO)copper(II) ethanol hemisolvate forms a hydrogen-bonded chain.
abstract: In the crystal structure of [Cu(CF(3)SO(3))(C(2)N(3))(C(8)H(7)N(5))(2)].0.5C(2)H(6)O, the Cu(II) atom adopts a distorted octahedral geometry, with the basal plane formed by two N atoms of one dipyrimidinylamine ligand, one N atom of the second pyrimidine ligand and a nitrile N atom of the dicyanamide anion [Cu-N = 1.972 (2)-2.021 (2) A]. The apical positions are occupied by an N atom of the second ligand [Cu-N = 2.208 (2) A], and an O atom of the trifluoromethanesulfonate anion [Cu-O = 2.747 (2) A] at a semi-coordination distance. Pairs of inversion-related N-H.N hydrogen bonds of the so-called Watson-Crick type, augmented by two C-H.N contacts, link adjacent complexes into an infinite one-dimensional chain running in the [101] direction.
