Two crystalline phases of chlorotris(2-pyridyl)phosphinegold(I)

Synthesis and Reactions of Mixed N,P Ligands

“…Complex 6b crystallises as a discrete monomer with the Au atom adopting a linear geometry [P–Au–Cl 178.74(9)°]. The Au–P and Au–Cl distances of 2.245(2) and 2.296(2) Å are unexceptional and compare well to those found in related two‐coordinate phosphane complexes such as i Bu 3 PAuCl,18 Et 3 PAuCl,19 Ph 3 PAuCl,20 (2‐Pyr) 3 PAuCl21 or i Pr 3 PAuCl 22. The short C2–N [1.266(6) Å] and long C1–C2 [1.558(6) Å] distances are consistent with the alkyl substituent at P being an iminoalkyl.…”

Tris(2-imidazolyl)phosphine hemihydrate

“…Structure B might be stabilized by hydrogen bonding in tings 1 and 2, but the effect is also observed in ring 3 where no hydrogen bonding is present. The P--C distances lie between those observed for the protonated and unprotonated tings in the phosphinic acid and are shorter than those observed in tris(2-pyridyl)phosphine (average 1.811 versus 1.837 A) (Lock & Turner, 1987).…”
