A new complex of N-thiophosphorylthiourea PhNHC(S)NHP(S)(OiPr)(2) (HL) of formula [(Cu3L3)(2)] has been synthesized and characterized by single crystal X-ray diffraction, FT-IR, H-1, P-31 NMR in solution and by P-31 CPMAS NMR spectroscopy in the solid state. A comparison of the structure and the spectral parameters of [(Cu3L3)(2)] with those of the mononuclear analogue [Cu(PPh3)(2)L] was performed. In the solid state the aggregate [(Cu3L3)(2)] represents the first example of a spontaneous "side-by-side" association of two neutral cyclic [Cu3L3] moieties using two Cu-S-Cu bridges formed by the sulfur atoms of the PS-groups. The values of the (1)J(P-31-Cu-63,Cu-65) and (2)J(P-31-P-31) coupling constants of the [Cu(PPh3)(2)](+) moiety in the solid state spectra are reported. (C) 2008 Elsevier B. V. All rights reserved.
