(1,10-Phenanthroline-²N,N')(triphenylphosphine-P)silver(I) perchlorate acetonitrile hemisolvate

A. D. Khalaji, M. Amirnasr and J.-C. Daran

Abstract: The asymmetric unit of the title compound, [Ag(C₁₂H₈N₂)(C₁₈H₁₅P)]ClO₄·0.5CH₃CN, consists of two [Ag(phen)(PPh₃)]⁺ complex cations (phen is 1,10-phenanthroline), two perchlorate anions and one acetonitrile solvent molecule. The Ag^I atoms assume a Y-shaped nearly planar geometry in which the metal ion is ligated by two phen N atoms and one P atom of a triphenylphosphine ligand. The two cations in the asymmetric unit are stacked in an inverse fashion through strong offset - stacking interactions with a face-to-face distance of 3.479 (2) Å, leading to accessible voids for acetonitrile solvent molecules. The disordered solvent molecule could not be satisfactorily modelled and, therefore, it was eliminated from the final refinement.
