Di-μ-acetato-κ(4) O:O′-bis­[(1,10-phenanthroline-κ(2) N,N′)(tri­fluoro­methane­sulfonato-κO)copper(II)]

The complete molecule of the title compound, [Cu(2)(C(2)H(3)O(2))(2)(CF(3)O(3)S)(2)(C(12)H(8)N(2))(2)], is completed by the application of a twofold rotation and comprises two Cu(II) ions, each of which is penta­coordinated by two N atoms from a bidentate 1,10-phenanthroline (phen) ligand, two O atoms from acetate ligands and an O atom from a tri­fluoro­methane­sulfonate anion, forming a (4 + 1) distorted square-pyramidal coordination geometry. The Cu(II) ions are connected by two acetate bridges in a syn–syn configuration. The F atoms of the tri­fluoro­methane­sulfonate ligands are disordered, with site-occupation factors of 70 and 30. The molecular structure is stabilized by intra­molecular face-to-face π–π inter­actions with centroid–centroid distances in the range 3.5654 (12)–3.8775(12) Å. The crystal structure is stabilized by C—H⋯O interactions, leading to a three-dimensional lattice structure.
