Structural characterization of copper–indium chalcopyrite precursors (PPh3)2CuIn(ER)4 [R = CH3, E = S and R = Ph, E = S and Se]

Polymeric cobalt(ii) thiolato complexes – syntheses, structures and properties of 1∞[Co(SMes)2] and 1∞[Co(SPh)2NH3]

“…4,5 New developments in the latter respect came from the utilization of small clusters as building blocks for the formation of nanoparticles with controllable size and shape through photolytic decomposition and solvothermal synthesis. [6][7][8][9][10] For some time metal chalcogenolato complexes have also been investigated due to oligomeric (e.g. ring-like) or polymeric structures.…”

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

“…The inner angle Se1-In-Se1 i (98.0 ) of the "CuSe 2 In" ring and outer angle Se2-In-Se2 i (111.1 ) formed by the terminal selenolate groups are less deviated from the ideal tetrahedral angle in comparison to the corresponding angles (96.1 and 116.6) in the reported complex [(Ph 3 P) 2 Cu(m-SePh) 2 In(SePh) 2 ]. 15 The spacer CH 2 group of the benzylselenolate ligand in the present complex helps to minimise the steric repulsion between the bulkier groups which is manifested in the reduced non-bonded Cu/In distance of about 3.35Å, compared to analogous phenyl selenolate complex (3.50Å). 15 The benzyl groups adopt anti conformation and a two-fold symmetry axis exist along the Cu-In bond in the molecular structure.…”

As expected the tetrahedral Cu center is more distorted due to the two bulkier phosphines as revealed by the P1-Cu-P1 i angle measuring 122.2 .…”

“…In contrast to the complexes of Cu and In using ethyl selenolate/phenyl selenolate, 5,13,15 the pyridylselenolates of Cu and In do not react with each other to form heterometallic chalcogenolates. 16 This non reactivity can be attributed to the presence of the pyridine donors, which compete effectively with bridging selenolate ligands for access to the metal coordination sphere to form molecular indium compounds and to the stabilizing inuence of the Cu-Cu bonds in the copper compounds.…”

“…10 The solvothermal route under mild reaction conditions using single-source precursors (SSPs) has emerged as highly efficient tool for the controlled preparation of nanostructures. Since the rst report of [(PPh 3 ) 2 CuIn(SEt) 4 ] in 1993 by Hirpo et al, 13 the complexes of the general formula [(PR 3 ) n CuM(ER 0 ) 4 ] (R, R 0 ¼ alkyl, aryl) 5, [13][14][15][16] have been extensively investigated as SSPs for the preparation of thin lm of CuME 2 using CVD technique. A few such SSPs have also been used to prepare the nanoparticles of CuME 2 at reduced temperature.…”
