fac -[1,2-Bis(pyridin-4-yl)ethane-κ N ]tricarbonyl(1,10-phenanthroline-κ 2 N , N ′)rhenium(I) hexafluoridophosphate acetonitrile monosolvate

The asymmetric unit of the title compound, [Re(C 12 H 8 N 2 )(C 12 H 12 N 2 )(CO) 3 ]PF 6 .·CH 3 CN, contains one cation, one hexafluoridophosphate anion and one acetonitrile solvent molecule. The Re I ion is coordinated by two N atoms from the 1,10-phenanthroline ligand and one N atom from the 1,2-bis(pyridin-4-yl)ethane ligand [mean Re—N = 2.191 (15) Å] and by three carbonyl ligands [mean Re—C = 1.926 (3) Å] in a distorted octahedral geometry. The electrostatic forces and weak C—H...F(O) hydrogen bonds pack cations and anions into the crystal with voids of 82 Å 3 , which are filled by solvent molecules. The crystal packing exhibits short intermolecular O...O distance of 2.795 (5) Å between two cations related by inversion.
