The use of metal complexes to deposit metal chalcogenide thin films and nanoparticles
… discussed. The X-ray structure of the platinum complex shows a square-planar conformation whereas the six membered PtSe2P2N ring adopts a distorted "boat" conformation. The third chapter describes the deposition of metal sulphide thin films from [M(S2COR)2], were M = Pt, Pd, Ni, Cd, Co, Cu and R …
