Synthesis, structural characterization, photoluminescence and thermal properties of [(Ph3P)2Cu(μ-SeC{O}R)2Cu(PPh3)]†
Abstract
A number of neutral unsymmetrical dimers [(Ph3P)2Cu(μ-SeC{O}R)2Cu(PPh3)]
(R = C6H5
(1), C6H4-Me-4 (2), C6H4-OMe-4 (3), C6H4-Cl-4 (4), C6H4-F-4 (5) and CH3
(6)) were synthesized in moderate yield, and characterized by analytical and spectroscopic techniques including O groups have anti stereochemistry
with respect to the Cu2Se2 ring while MeC
O groups have syn configuration in 6. A weak C–H⋯O
C intramolecular hydrogen bond present between the two selenoacetato
