Abstract
New complexes of Cu(I) and Ru(II) with elemental (white) phosphorus (P4), [Cu(C5H-i-Pr4)(η2-P4)], [Cu(C5H-i-Pr4)(μ,η2:1-P4)Cu(C5H-i-Pr4)], and [Ru(C5Me5)(PCy3)(η2-P4)Cl], are synthesized with tetraphosphorus molecule as bidentate η2-ligand. The complexes are obtained by reacting elemental phosphorus with the Cu carbonyl(tetraisopropylcyclopentadienyl) complex [Cu(C5H-i-Pr4)(CO)] or with Ru(II) (pentamethylcyclopentadienyl)(tricyclohexylphosphine) chloride, [Ru(C5Me5)(PCy3)Cl]. The structures and compositions of the obtained complexes are studied by 1H, 31P NMR method and elemental analysis. The P4 molecule is connected to Cu(I) and Ru(II) fragments through the P-P edge due to a side coordination.
