Popis:	Mononuclear palladium(II) complexes of the type [Pd(SePh)2L2] [where L = PMe3, PEt3, P(n-Bu)3, PMePh2 or TPA (1,3,5-triaza-7-phosphaadamantane)] have been prepared and characterized by elemental analysis, 1H, 13C{1H} and 31P{1H} NMR data and in the case of [Pd(SePh)2(P(n-Bu)3)2] by single-crys diffraction methods. Crystals of [Pd(SePh)2(P(n-Bu)3)2] are triclinic, space group P 1 , a = 8.4798(7), b = 10.3002(15), c = 12.254(2) A , α = 77.957(15), β = 85.806(11), γ = 83.550(9)°, Z = 1 . The structure was refined by full-matrix least-squares calculations on F2 to final R values Robs = 0.0267 (for 3187 reflections with I⩾2σ(I)) and wR(F2) = 0.0657 (for all 4549 measured reflections). The structure determination shows that the Pd atom lies on an inversion centre so that the coordination geometry is necessarily trans and planar. Main bond lengths are Pd-P 2.3334(7) and PdSe 2.4609(4)A.
