trans-Bis[5-(4-fluoro­phen­yl)tetra­zol­ato]bis­(triphenyl­phosphine)platinum(II)

S. Mukhopadhyay, J. Lasri, M. F. C. Guedes da Silva, M. A. J. Charmier and A. J. L. Pombeiro
The diazide platinum(II) complex, [Pt(N3)2(PPh3)2], reacts with 4-FC6H4CN under microwave irradiation to give the corresponding neutral title bis­(tetra­zolate) complex trans-[Pt(N4CR)2(PPh3)2] or [Pt(C7H4FN4)2(C18H15P)2]. The PtII atom lies on a crystallographic inversion centre and is coordinated by two N atoms and two P atoms in a slightly distorted square-planar environment. The unique tetra­zolate ring is essentially planar and the corresponding C[pdbond]N and N[pdbond]N bond distances lie in the range 1.317 (3)–1.349 (3) Å.

Comment top

Among heterocyles tetrazoles are an important species as they find use in e.g. material science, pharmaceutical chemistry and as precursors for various types of nitrogen containing heterocyles (Himo et al., 2003). Cycloaddition between an organic azide (RN3) and an organic nitrile (RCN) or isonitrile (RNC) provides tetrazoles, though in harsh conditions (Huisgen, 1968). However, the formation of substituted tetrazoles has been achieved by using a transition metal coordinated azide and free organonitriles (Kukushkin & Pombeiro, 2002) or isonitriles (Kim et al., 2002). Among several transition metals, platinum(II) has been used (Fehlhammer et al. 1983). The existence of several possible isomers for cycloadded compounds in solution was reported by them but the crystal structures were not determined. Herein we report the crystal structure of the tetrazolato complex trans-[Pt(5-p-fluorophenyltetrazolato)2(PPh3)2] (I).

Complex (I) (Fig. 1) is square-planar with the platinum(II) ion in a special position and coordinated to two N2 atoms of the tetrazol moieties and two phosphorus of the phosphines. The tetrazolato ring is nearly planar with bond lengths in the range 1.317 (3) - 1.349 (3) Å, which is similar to those of complexes trans-[Pt(N4CR)2(PPh3)2] (R = Ph or 4-ClC6H4), cis-[Pt(N4CPh)2(2,2-bipy)] and trans-[Pt(C≡ N)(ethyltetrazolato) (PPh3)2)] (Mukhopadhyay et al., 2007). All other bond lengths are normal (Allen et al., 1987; Orpen et al., 1989).

Experimental top

The title complex was prepared by dissolving cis-[Pt(N3)2(PPh3)2] (0.080 g, 0.10 mmol) and 4-fluorobenzonitrile (0.137 g, 1.00 mmol) in 5 ml of DMF and irradiating the solution with focused microwave for 1 h at 373 K. The product precipitated as a white solid which was washed several times with diethyl ether and dried in vacuo. Single crystals were grown by keeping the mother liquid at 277 K for several days. IR (KBr pellet): 1637 ν(C═ C). Anal. Calc. for Pt50H38N8P2F2:C, 57.41; H, 3.63; N, 10.71%. Found: C,57.12; H 3.67; N10.59%. Characterization by NMR spectroscopy was not possible due to the very poor solubility of the complex in common solvents.

Refinement top

All H atoms were placed in calculated positions with C—H = 0.95 Å and were included in the riding-motion approximation with Uiso(H) = 1.2Ueq(C).

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.
