Diphenyl(5-pyrimidyl)phosphine (L) has been synthesized and its coordination abilities toward Cu(I) and Au(I) have been surveyed. The reaction of L with Cu(MeCN)(4)BF4 or CuI produces 1D polymers [Cu(L)(MeCN)(2)]BF4 and [Cu2I2(L)(2)], or 2D grids [Cu2I2(L)(2)], wherein P,N-bridging pattern of the ligand always appears. Treatment of L with 1 or 3 equiv. of Au(tht)Cl affords linear [Au(L)Cl] or trigonal pyramidal [Au(L)(3)Cl] complexes, in which the ligand is P-coordinated to Au(I). At 300 K, 1D polymers [Cu(L)(MeCN)(2)]BF4 and [Cu2I2(L)(2)] exhibit weak yellow and moderate green emission, respectively, which strongly enhances upon colling to 77 K. Complex [Au(L)(3)Cl] at 300 K emits strong sky-blue phosphorescence (lambda(em) = 492 nm) with the quantum yield of 50%.
