Three silver(I) complexes, [Ag(ca2en)(PPh3)]ClO4 (1), [Ag(ca2en)(PPh3)2]ClO4 (2) and [Ag(ca2en)2]ClO4 (3), where ca2en = N,N'-bis(trans-cinnamaldehyde)ethylenediimine, have been synthesized and characterized spectroscopically. The crystal structure of (1) was determined by X-ray diffraction methods. Crystal data for 1: C38H35AgClN2O4P, triclinic, P1, a = 12.086(2), b = 18.204(2), c = 8.550(2) Å, α = 102.69(1), = 105.85(1), = 91.47(1)°, V = 1758.0(5) Å3, Z = 2, R(F) = 0.070, wR (F) = 0.064, T = 296 K. The coordination geometry of the Ag atom is distorted trigonal involving two N atoms of ca2en and one P atom of triphenylphosphine (PPh3).
