trans-Dichlorobis(triphenylphosphine-P)platinum(II)

Abstract

Two different crystals (A and B) were used to structurally characterize trans‐[PtCl2(PPh3)2] and to study random and systematic errors in derived parameters. The compound is isomorphous with trans‐[PdCl2(PPh3)2] and with one of the polymorphs of trans‐[PtMeCl(PPh3)2] reported previously. Half‐normal probability plot analyses based on A and B show realistic s.u.'s and negligible systematic errors. R.m.s. calculations give very good agreement between A and B, 0.0088 Å. Important geometrical parameters are Pt—P = 2.3163 (11) Å, Pt—Cl = 2.2997 (11) Å, P—Pt—Cl = 87.88 (4) and 92.12 (4)°. Half‐normal probability plots and r.m.s. calculations were also used to compare the title compound with the palladium analogue, showing small systematic differences between the compounds. The torsion angles around the Pt—P bond were found to be very similar to those reported for isomorphous complexes, as well as to the torsion angles around the Pt—As bond in trans‐[PtCl2(AsPh3)2]. The NMR coupling constants for the title compound are similar to Pt—P coupling constants reported for analogous trans complexes.

Synthesis, characterization, luminescence and nonlinear optical (NLO) properties of truxene-containing platinum(II) alkynyl complexes

“…The platinum atoms in complex 4 adopted essentially a trans-square planar arrangement with PePteC angles in the range of 84.7(5) and 95.0(5) . Such slight distortion around the coordination plane was likely due to the coordination constraints imposed by the bulky triphenylphosphine ligands [93,94] (6) and 2.298(4) Å, which were slightly shorter than those reported previously [83,95]. The bond angles about the alkynyl ligand and the platinum metal centres were in the range of 168.8(15)e170.9 (18) , which were close to the ideal sp-hybridized carbon bond angle and further confirmed the s-bonded nature of the alkynyl groups in the complex.…”

“…The Pt-P bond lengths in trans-PtCl 2 (Ph 2 P n C 10 F 21 ) 2 are 2.3027(6) and 2.3039(6) Å. These are shorter than the corresponding bond lengths in trans-PtCl 2 (PPh 3 ) 2 (2.319(3) and 2.316(3) Å) [21]. The P-CF 2 bond lengths in trans-PtCl 2 (Ph 2 P n C 10 F 21 ) 2 are 1.913(3) and 1.909(3).…”
