Group 10 and 11 metal complexes of a multidentate phosphorus-nitrogen donor ligand tris(4-methylpiperazin-1-yl)-phosphane, P(NC4H 8NMe)3 (1) are reported. The reactions of 1 with an equimolar amount of CuX (X = Cl, Br and I) afford tetranuclear cubane-like complexes [(CuX)-{P(NC4H8NMe)3}]4 (2, X = Cl; 3, X = Br and 4, X = I) in excellent yield. Treatment of 1 with AuCl(SMe2) produces a mononuclear complex, [(AuCl){P(NC 4H8NMe)3}] (5). Reaction of 1 with AgCN produces a 2D AgI polymeric sheet, [(AgCN)2-{P(NC4H 8NMe)3}]n (6) in moderate yield. The similar 1:1 reactions of 1 with AgX (X = Cl and Br) furnish dinuclear complexes, [(AgX){P(NC4H8NMe)3}]2 (7, X = Cl and 8, X = Br). The 2:1 reactions of 1 with [M(COD)Cl2] (M = Pd or Pt) afford [{P(NC4H8NMe)3}2MCl 2] (9, M = Pd and 10, M = Pt) in quantitative yield. The molecular structures of complexes 1-3 and 6 are established through single-crystal X-ray diffraction studies. The catalytic activity of the PdII complex 9 has been investigated in Suzuki cross coupling reactions. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
