Copper(I) halides with N1-substituted pyridine-2-carbaldehyde thiosemicarbazones [(C5H4N)HC2=N 3N2H-C1(=S)N1HR] in the presence of Ph3P have formed complexes of stoichiometry, [CuX(Hpytsc-N 1HR)(Ph3P)2] [X, R; Br, Me (1); Br, Et (2), Cl, Ph (3·CH3CN)]. All these complexes are characterised by elemental analysis, IR and NMR (1H, 31P) spectroscopy and X-ray crystallography. The role of substituents at N1 atom of pyridine-2-carbaldehyde thiosemicarbazones in intermolecular interactions in copper(I) complexes is described. A 1D polymer of compound 1 is formed by intermolecular CH(methyl)···π(py) interactions. The hydrogen atoms of EtN1H and ethyl group interact with the phenyl ring of PPh3 {via EtN 1H···π(Ph), H2CH (Et)···π(Ph)} to form a 1D polymer of 2. A 2D sheet arrangement of compound 3 is formed by pyridyl-phenyl (CH (py)···π(Ph)) interactions along the a axis and phenyl-phenyl [CH (Ph)···π(Ph)] interactions (phenyl at N1 with phenyl of PPh3) along the b axis.
