Synthesis of heteroligand complex Nd(Phen){( iso -C4H9)2PS2}2(NO3). Crystal structure of [Nd(Phen){( iso -C4H9)2PS2}3] and luminescent properties of these compounds

Russian Journal of Coordination Chemistry (impact factor: 0.55). 11/2008; 34(12):931-937. DOI:10.1134/S1070328408120105 pp.931-937

ABSTRACT The heteroligand complex Nd(Phen){(iso-C4H9)2PS2}2(NO3) (I) was synthesized and its IR spectrum was analyzed. The anions (iso-C4H9)2PS2/− and N3/− act as bidentate cyclic ligands. The single crystals of [Nd(Phen){iso-C4H9)2PS2}3] (II) were obtained on evaporation of a solution of complex I in a mixture CH2Cl2-hexane and were studied by X-ray diffraction. Crystals II are triclinic: a = 10.5509(5); b = 14.7432(8), c = 16.8503(10) Å; α = 102.882(2)°, β = 97.211(2)°, γ= 108.087(2)°, V = 2374(2) Å3, Z = 2, ρ(calcd.) = 1.332 g/cm3, space group $

. The coordination polyhedron of the Nd atom in a separate mononuclear molecule II is a distorted dodecahedron N2S6. The molecules are bound by weak van der Waals and π-π interactions. The photoluminescence spectra of complexes I, II were measured and interpreted.
