Crystal structure of bis(acetonyltriphenylphosphonium) tetrachloridocobaltate(II)

Abstract

The complex title salt, (C21H20OP)2[CoCl4], is the reaction product of CoCl2 with acetonyltri­phenyl­phospho­nium chloride in aceto­nitrile. In the anion, the CoII atom exhibits a typical tetra­hedral environment, with Co—Cl distances ranging from 2.2721 (6) to 2.2901 (6) Å, and with Cl—Co—Cl angles ranging from 106.12 (2) to 112.24 (2)°. The two phospho­nium cations likewise show the expected tetra­hedral configuration, with P—C distances ranging from 1.785 (2) to 1.8059 (18) Å and C—P—C angles ranging from 106.98 (8) to 112.85 (15)°. The mol­ecules inter­act in the lattice mainly through Coulombic and van der Waals forces because there is no particular polarity to the charges carried by the cations or anion. In the crystal, the cations and anions are arranged in sheets parallel to (001).

Acetonyltriphenylphosphonium 2,3,5-triphenyltetrazolium tetrachloridocuprate(II)

“…49 (2) ] in normal ranges for the [CuCl 4 ] 2À complex anion (Clay et al, 1975;Laus et al, 2015). The P-C distances within the acetonyl triphenylphosphonium cation are similar to those reported for the same cation (Diop et al, 2013(Diop et al, , 2015. The range for the C-P-C angles [107.07 (9)-113.36 (10) ] indicate a small variation of the geometry for this cation.…”

“…Likewise, a few compounds with an acetonyl triphenylphosphonium or 2,3,5-triphenyltetrazolium cation have also been reported (Diop et al, 2013(Diop et al, , 2015Zhang et al, 2007). To expand on the available data on both the [CuCl 4 ] 2À anion as well as that on acetonyltriphenylphosphonium and 2,3,5-triphenyltetrazolium cations, we have initiated in this work the study of the interactions between CuCl 2 Á2H 2 O, acetonyl triphenylphosphonium chloride and 2,3,5-triphenyltetrazolium chloride, expecting the presence of both cations in the resulting compound.…”

“…Acetonyltriphenylphosphonium can be used as a counter ion to stabilize an anion but may be an O-donor ligand coordinating to metal centers with its oxygen O atom. Very few crystalline compounds relating to acetonyltriphenylphosphonium have been encountered in the literature [12][13][14][15].…”
