Synthesis and structure of [(Ph₃P)₂Cu(μ-SeCH₂Ph)₂In(SeCH₂Ph)₂] as a single-source precursor for the preparation of CuInSe₂ nano-materials.

ABSTRACT: The reaction of freshly prepared Na[In(SeCH₂C₆H₅)₄] with the mixture of CuCl and triphenylphosphine in methanol yielded [(PPh₃)₂CuIn(SeCH₂C₆H₅)₄]. The X-ray structure of the complex revealed the monomeric form of [(Ph₃P)₂Cu(μ-SeCH₂Ph)₂In(SeCH₂Ph)₂] consisting of tetrahedral Cu(i) and In(iii) centers, bridged by two benzyl selenolate ligands. The complex on pyrolysis in a furnace or in oleylamine/HDA yielded tetragonal CuInSe₂. The morphology and composition of nanostructures were investigated by pXRD, SEM, TEM and EDX analysis. The band gap of the CuInSe₂ nanostructures, obtained from pyrolysis
