Description
Summary:Complexes (A)[Gd(L) 4 ] and [Gd(Phen)(L) 3 ] (L = iso -Bu 2 PS 2 - , C 4 H 8 NCS 2 - ; A = NH 4 + , Et 4 N + ) are synthesized. The crystal structure of compound [Gd(Phen)( iso -Bu 2 PS 2 ) 3 ] · MeCN is determined by X-ray diffraction analysis (CIF file CCDC no. 1455418). The structure consists of molecules of the mononuclear complex [Gd(Phen)( iso -Bu 2 PS 2 ) 3 ] and MeCN. The coordination polyhedron N 2 S 6 of the Gd atom is a distorted antiprism. The complexes exhibit phosphorescence in a range of 400–600 nm. The energies of the triplet levels of the ligands C 4 H 8 NCS 2 - (23336 cm –1 ) and iso -Bu 2 PS 2 - (23506 cm –1 ) are determined from the phosphorescence spectra of complexes (A)[Gd(L) 4 ] in frozen ethanol (77 K).
