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

The asymmetric unit of the title compound, [Re(C12H8N2)(C12H12N2)(CO)(3)]PF6 center dot CH3CN, contains one cation, one hexa-fluorido-phosphate anion and one aceto-nitrile solvent mol-ecule. 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) angstrom] and by three carbonyl ligands [mean Re-C = 1.926 (3) angstrom] in a distorted octa-hedral geometry. The electrostatic forces and weak C-H center dot center dot center dot F(O) hydrogen bonds pack cations and anions into the crystal with voids of 82 angstrom(3), which are filled by solvent mol-ecules. The crystal packing exhibits short inter-molecular O center dot center dot center dot O distance of 2.795 (5) angstrom between two cations related by inversion.
