Abstract
Abstract Reactions of [Cu(tmtp)I] 4 (tmtptri- m -tolylphosphine) with heterocyclic thiones (L) (Lpyridine-2- thione (py2SH), pyrimidine-2-thione (pymtH), 1,3-thiazolidine-2-thione (tzdtH), 1-methyl-1,3- imidazoline-2-thione (meimtH), benz-1,3-imidazoline-2-thione (bzimtH 2 ) and quinoline-2-thione (qntH)) yield binuclear complexes of the general formula [Cu(tmtp)(L)I] 2 . The complexes have been characterized by elemental analyses and their IR, UV-Vis and 1 H NMR spectroscopic data. The photolysis of these complexes in dichloromethane solutions has been investigated. The crystal structure of [Cu(tmtp)-(py2SH)I] 2 has been determined by single-crystal X-ray diffraction methods. The orange crystals are triclinic, space group P 1 with a =9.9881(6), b =10.8255(5), c =13.5355(8) A, α=77.268(2),β=94.409(2), γ=68.102(2)°, D calc =1.543 Mg m -3 , V =1303.94(2) A 3 and Z =1. The molecule contains a planar Cu 2 I 2 moiety with Cu-I bond lengths of 2.690(1) and 2.695(1) A. The Cu-P and Cu-S distances are 2.241(1) and 2.303(1) A, respectively. The Cu···Cu separation is 3.119(1) A.
