Two binuclear Ag-1 complexes, [{Ag(dppp)}(2)] (NO3)(2) (1) and [{Ag(dp
pb)}(2)(NO3)](2) (2) (dppp = Ph(2)P(CH2)(3)PPh(2), dppb = Ph(2)P(CH2)(
4)PPh(2)], were synthesized and characterized by elemental analysis, t
.g., i.r. and P-31-n.m.r. spectra. Single crystals of complex (2) were
obtained from MeOH-CHCl3. The X-ray crystal structure shows that the
dppb ligand is bidentate, with two ligands bridging two metal ions to
form a centrosymmetric dimer.
