Abstract

Abstract: The present work is directed towards preparation by means of alternating current electrochemical synthesis, structural, and optical property characterization of Cu(I) π-coordination compounds [Cu( papt )NO3 ] (1 ), [Cu2 ( papt )2 Cl2 ] (2 ), [Cu2 ( papt )2 Br2 ] (3 ), [Cu2 ( eapt )2 Cl2 ] (4 ), and [Cu2 ( eapt )2 Br2 ] (5 ) with disubstituted pseudothiohydantoins, (2 Z )-2-(phenylimino)-3-allyl-1, 3-thiazolidin-4-one ( papt ) and (2 Z )-2-[(2-hydroxyethyl)imino]-3-allyl-1, 3-thiazolidin-4-one ( eapt ). All coordination compounds crystallize in the centrosymmetric monoclinic P 21 / n space group, 2 and 3, as well as 4 and 5 are isostructural to each other. Cu(I) in all the structures have trigonal–pyramidal environment formed by N-imino and allyl C = C double bond of the chelate organic ligand and two oxygens of NO3 – in 1 or two halides in 2 –5 . Crystal packing of 2 and 4 were analyzed using energy framework computational analysis to examine differences in crystal structures of papt- and eapt -based coordination compounds, which could be explained by the difference in weak interactions of phenyl and 2-hydroxyethyl groups. The third-order nonlinear optical features for 1 and 2 are studied at 1064 nm generated by a nanosecond pulsed Nd:YAG laser. Abstract :
