In the title compound, [TeBr4(C22H23OP)]·CH3CN, the Te atom exhibits a square-pyramidal coordination with an apical Te—C bond and four basal Te—Br bonds. The conformation of the aliphatic C—C—C—C chain is gauche [torsion angle = −67.7 (8)°]. A weak C—H⋯Br inter­action helps to establish the conformation. In the crystal, there is a weak secondary bonding inter­action [Te⋯N = 3.456 (11) Å] between the Te atom and the N atom of the solvent mol­ecule, which completes a distorted TeNCBr4 octa­hedron. Inversion dimers linked by pairs of C—H⋯Br inter­actions are also observed.

Comment top

The formation of Ph3PO(CH2)4TeBr4 has been reported earlier by us (Kunnari et al. 2001). The formally zwitterionic compound was isolated by treating TeBr4 with an equimolar amount of triphenylphosphine in tetrahydrofuran. The compound was crystallized from dichloromethane and its molecular structure was determined as a dichloromethane solvate. The title compound was recrystallized from acetonitrile and consequently contains acetonitrile solvent molecules. It is isomorphic with the CH2Cl2 solvate.

The molecular structure of the title compound indicating the numbering of the atoms is shown in Fig. 1. The Te—Br bond lengths range from 2.6652 (10) to 2.7201 (10) Å. The Te—C bond length is 2.176 (7) Å and the P—O bond length is 1.568 (5) Å. These can be compared to the bond lengths in the corresponding CH2Cl2 solvate in which the Te—Br bond lengths range 2.6776 (8) - 2.6952 (9) Å, Te—C bond length is 2.177 (6) Å, and P—O bond length is 1.581 (4) Å (Kunnari et al. 2001).

The closest internuclear contact from tellurium atom to the nitrogen atom of the solvent molecule is 3.456 (11) Å expanding the square pyramidal coordination polyhedron into a distorted octahedron. This is typical for Te···N secondary bonding interactions (Cozzolino et al. 2011). Interestingly, the Te..N interaction is stronger [Pauling (1960) bond order is 0.15] compared to the Te..Cl interaction in the CH2Cl2 solvate (Kunnari et al. 2001), for which the contact is 4.175 (3) Å corresponding to the Pauling bond order of only 0.09. This is also reflected in the C—Te—E (E = N, Cl) bond angles which are 165.0 (3) and 144.0 (1) °, respectively.

Intra- and intermolecular hydrogen bonds link the zwitterions into a three- dimensional network, as shown in Fig. 2. The shortest intermolecular C—H···Br contacts span a range of 2.75 (1)–2.96 (1) Å and the short C—H..N contacts are 2.68 (1) and 2.96 (1) Å.

Yellow plates of the title compound were obtained from the acetonitrile solution of Ph3PO(CH2)4TeBr4 by slow evaporation of the solvent.

Refinement top

H atoms were positioned geometrically and refined using a riding model with C—H = 0.99 Å and with Uiso(H) = 1.2 Ueq(C), 0.98 Å and Uiso(H) = 1.5 Ueq(C) and 0.95 Å and Uiso(H) = 1.2 Ueq(C)for the methylene, methyl and aromatic H atoms, respectively.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
