Bis­[bis­(pyrimidin‐2‐yl‐κN)­amine](dicyan­amido‐κN1)(tri­fluoro­methanesulfonato‐κO)copper(II) ethanol hemisolvate forms a hydrogen‐bonded chain

In the crystal structure of Cu(CF₃SO₃)(C₂N₃)(C₈H₇N₅)₂]·0.5C₂H₆O, 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) Å]. The apical positions are occupied by an N atom of the second ligand Cu—N = 2.208 (2) Å], and an O atom of the tri­fluoro­methane­sulfonate anion Cu—O = 2.747 (2) Å] 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.
