Synthesis, spectral, thermal, and a crystalline structure of complexes containing [MeC(CH2PPh2)3Cu(I)]

The preparation of new [MeC(CH2PPh2)3CuCl] 1 and its derivatives was carried out directly by mixing of CuCl and MeC(CH2PPh2)3 ligand in dry THF, the neutral precursor 1 served to prepare [MeC(CH2PPh2) 3Cu(NCCH3)]BF4 2 and [MeC(CH 2PPh2)3Cu(PCH2Ph) 3]BF4 3. These complexes are characterized on the basis of elemental analysis, IR, EDS, 1H, 13C and 31P{1H}NMR, FAB-MS, TG/DTA and single-crystal X-ray diffraction studies. Complex 1 crystallizes in the Orthorhombic unit cells with the space group Pna2(1). The structural behavior of MeC(CH2PPh 2)3 ligand in the formed complexes during the coordination reaction was monitored by 31P{1H}NMR in CDCl3 at room temperature for the first time.

Synthesis, reactivity and comparative structural studies on copper(I) and gold(I) halo complexes with tripodal polyphosphines in 1:1 metal to ligand ratio. The X-ray crystal structures of three mononuclear neutral compounds

Cu(I) and Au(I) halides interact with equimolecular amounts of tripodal polyphosphines as CH3C(CH2PPh2) 3(CP3) in CHCl3, N(CH2CH 2PPh2)3(NP3) in CH 2Cl2 or CH2Cl2-S (S=MeOH, Et 2O) and P(CH2CH2PPh2)3 (PP3) in CH2Cl2 to form Cu(CP3)X [X=Br (1), I (2)], [Au3(CP3)2Cl2]Cl (3), [Au3(CP3)3X]X2 [X=Br (4), I (5)], Cu(NP3)X [X=Cl (6), Br (7), I (8)], [Au2(NP 3)2]X2 [X=Cl (9), Br (10)], Au(NP 3)I (11), [Cu2(PP3)2X]X [X=Cl (12), Br (13)] and [Au2(PP3)2]X2 [X=Br (14), I (15)]. Complexes 1, 7 and 11 were shown by X-ray diffraction to consist of neutral monomers with distorted tetrahedral geometry around the metal and the phosphine acting as tridentate chelating ligand. The mass spectra, conductivity measurements and 31P{1H} NMR studies for 9 and 10 are indicative of a coexistence with mononuclear forms. Complexes 3, 9 and 14 were also achieved in solution by addition of the appropriate polyphosphine to the compounds Au3(CP3)Cl3 (3a), Au3(NP3)Cl3 (9a) and Au 4(PP3)Br4 (14a), respectively, involving ring-closure reactions. Likewise, crystals of 1 were obtained both from solutions of this compound in CH2Cl2-EtOH and from solutions in CHCl3 of (1a)·2.5Et2O (1a=Cu 3(CP3)Br3). Further additions of the appropriate polyphosphine to 9 and 14 give complexes with new "MP 4" environments and dangling phosphorus that for 14 involve ring-opening processes. By reaction of 3 with CP3 the complex [Au3(CP3)3Cl]Cl2, isostructural with 4 and 5, is afforded in solution. The reaction of Cu(CP3)Cl (I) with CP3 followed by 31P{1H} NMR seems to occur with retention in part of the starting CuP3 core and formation of other species containing linear arrangements for Cu(I). No reaction was observed between 6 or 13 and NP3 or PP3, respectively.
