Structural characterization of copper-indium chalcopyrite precursors (PPh3)2CuIn(ER)4 [RÂ =Â CH3, EÂ =Â S and RÂ =Â Ph, EÂ =Â S and Se]

Full structural characterization of (PPh3)2CuIn(XR)4 [R = CH3, X = S and R = Ph, X = S and Se] Cu…In nonbonded distances (3.285-3.500 Å) depend on steric effects of the ligands Cu-In close contacts increase the Cu-X-In angles and decrease the μ-S-M-μ-S angles.114
