Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

New complexes of Cu(I) and Ru(II) with elemental (white) phosphorus (P 4 ), [Cu(C 5 H- i -Pr 4 )(η 2 -P 4 )], [Cu(C 5 H- i -Pr 4 )(μ,η 2:1 -P 4 )Cu(C 5 H- i -Pr 4 )], and [Ru(C 5 Me 5 )(PCy 3 )(η 2 -P 4 )Cl], are synthesized with tetraphosphorus molecule as bidentate η 2 -ligand. The complexes are obtained by reacting elemental phosphorus with the Cu carbonyl(tetraisopropylcyclopentadienyl) complex [Cu(C 5 H- i -Pr 4 )(CO)] or with Ru(II) (pentamethylcyclopentadienyl)(tricyclohexylphosphine) chloride, [Ru(C 5 Me 5 )(PCy 3 )Cl]. The structures and compositions of the obtained complexes are studied by 1 H, 31 P NMR method and elemental analysis. The P 4 molecule is connected to Cu(I) and Ru(II) fragments through the P-P edge due to a side coordination.
