文摘

The heteroligand complex Nd(Phen){(iso-C₄H₉)₂PS₂}₂(NO₃) (I) was synthesized and its IR spectrum was analyzed. The anions (iso-C₄H₉)₂PS_2/− and N_3/− 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) ?; α = 102.882(2)¡ã, β = 97.211(2)¡ã, γ= 108.087(2)¡ã, V = 2374(2) ?3, Z = 2, ρ(calcd.) = 1.332 g/cm3, space group _boxclose#xA; P\bar 1 . 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.
