The title compound was synthesized by the treatment of Chlorido{1-[2-(methylsulfanyl)phenyldiazenyl]phenyl–κ3C,N,S}platinum(II) with chlorinated acetonitrile following a reported procedure (Chattopadhyay et al., 1991) (Yield 74%).
H atoms were included at calculated positions as riding atoms with C–H set to 0.93 Å for (aromatic) and 0.96 Å for (CH3) H atoms, with Uiso(H) = 1.2Ueq(C) (1.5Ueq for methyl group). Some low-angle reflections were excluded from the refinement, as they were probably obscured by the beam stop.
The intramolecular C—H bond activation of aryl rings using platinum(II) is important in synthetic chemistry. There has been intense interest in C—H bond activation by platinum complexes (Lersch & Tilset, 2005; Rendina & Puddephatt, 1997). The oxidation of divalent cycloplatinates by halogens affords tetravalent cycloplatinates (Yahav et al., 2005) and the structures of few tetravalent platinum complexes have appeared in literature (Chattopadhyay et al., 1991; van Beek et al., 1986). Herein, we report the X-ray crystallographic study of the title compound.
The molecular structure of the title compound is shown in Fig. 1, with the atom numbering scheme. The platinum atom is hexa-coordinated with a donor set of six atoms in an approximately octahedral geometry. The packing arrangement of the title compound is shown in Fig. 2. The N=N bond length is slightly greater than the typical value (Chattopadhyay et al., 1991). The metal carbon and metal sulfur bond lengths are very close to the typical values; all the three Pt—Cl bond lengths are very close and are also close to the reported values (Chattopadhyay et al., 1991).
There are intra and intermolecular C—H···Cl hydrogen bonding interactions (Table 2, Fig. 3) in the title compound. A chain structure results by the intermolecular hydrogen-bonds where C13 atom in the molecule acts as a hydrogen-bond donor, via H13B, to the Cl1 atom of another molecule [Symmetry code: (i) -1 + x, y, z] (Table 2) (Fig. 3). A weak intermolecular π—π interaction (Bagchi et al., 2007) arranges the molecules in an anti parallel fashion (Fig. 4). The Cg3—Cg3ii [Symmetry code: (ii) -x, 1 - y, 1-z. Cg3 is the centroid of C1—C6 ring.] distance is 3.924 (8) Å and the perpendicular distance is 3.656 Å with a slippage of 1.424 Å.

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. |

The intramolecular C—H bond activation of aryl rings using platinum(II) is important in synthetic chemistry. There has been intense interest in C—H bond activation by platinum complexes (Lersch & Tilset, 2005; Rendina & Puddephatt, 1997). The oxidation of divalent cycloplatinates by halogens affords tetravalent cycloplatinates (Yahav et al., 2005) and the structures of few tetravalent platinum complexes have appeared in literature (Chattopadhyay et al., 1991; van Beek et al., 1986). Herein, we report the X-ray crystallographic study of the title compound.
The molecular structure of the title compound is shown in Fig. 1, with the atom numbering scheme. The platinum atom is hexa-coordinated with a donor set of six atoms in an approximately octahedral geometry. The packing arrangement of the title compound is shown in Fig. 2. The N=N bond length is slightly greater than the typical value (Chattopadhyay et al., 1991). The metal carbon and metal sulfur bond lengths are very close to the typical values; all the three Pt—Cl bond lengths are very close and are also close to the reported values (Chattopadhyay et al., 1991).
There are intra and intermolecular C—H···Cl hydrogen bonding interactions (Table 2, Fig. 3) in the title compound. A chain structure results by the intermolecular hydrogen-bonds where C13 atom in the molecule acts as a hydrogen-bond donor, via H13B, to the Cl1 atom of another molecule [Symmetry code: (i) -1 + x, y, z] (Table 2) (Fig. 3). A weak intermolecular π—π interaction (Bagchi et al., 2007) arranges the molecules in an anti parallel fashion (Fig. 4). The Cg3—Cg3ii [Symmetry code: (ii) -x, 1 - y, 1-z. Cg3 is the centroid of C1—C6 ring.] distance is 3.924 (8) Å and the perpendicular distance is 3.656 Å with a slippage of 1.424 Å.
