A series of new, relatively hydrophilic, N,N-dialkyl-N′-(2,2-dimethylpropyl)thioureas (HLn) (n = 1, N,N-dimethyl-; n = 2, N-pyrrolidyl-; n = 3, N-piperidyl-) and their corresponding cis-[M(Ln-S,O)2] [for M = Pt(II), Pd(II); n = 1–3] and fac-[Rh(Ln-S,O)3] (n = 2, 3) complexes have been prepared and characterised. The crystal and molecular structures of fac-tris(N-pyrrolidyl-N′-(2,2-dimethylpropyl)t
