Abstract
The sought-after member of the [(PDBP) n AgX] m (n, m=1,4; 2,2; 3,1; PDBP=5-Phenyldibenzophosphole, X=halides) series, the tetrameric [(PDBP)AgCl]4 cluster has been prepared and structurally characterized. The [P4Ag4Cl4] cluster core of [(PDBP)AgCl]4 bears striking similarity to that of [(Ph3P)AgCl]4.

In fact, the title compound was unintentionally prepared by us while using the [(PDBP)nAgX]m (X = Cl, Br, I) complexes in the syntheses of polyicosahedral Au-Ag clusters containing PDBP and X ligands.

Imaging plate data processing programs used: Rigaku's raxis2 package. Heavy atoms (Ag, Cl, and P) were located via direct methods and the carbon atoms were determined via successive Fourier syntheses. Anisotropic (heavy atoms)-isotropic (carbon atoms) refinement converged at R 1 = 0.074 for 3335 independent reflections (2ϑ ≤ 50°) with I > 2σ. Hydrogen atoms were calculated and fixed at ideal positions (C-H, 0.95 Å) with a common isotropic displacement factor of U iso = 0.1013 Å2. Structural solution and refinement programs used: teXsan of Molecular Structure Corperation.
