L3 and L4. Upon reaction with Na2PdCl4/[Pd(CH3CN)2Cl2], L1–L4 coordinated as a (O−, N, E) donor (E = S/Se) resulting in complexes [Pd(L–H)Cl] (1–4; L = L1–L4). The molecular structures of L1, 1 and 2 were established by single crystal X-ray diffraction. The palladium in 1 and 2 has a nearly square planar geometry. The Pd–S bond distance in 1 is 2.2648(14) Å and in 2, the Pd–Se bond distance is 2.3641(7)
