Sodium bicarbonate, NaHCO3, and dimethylgold(III) iodide, [(CH3)2AuI]2, (prepared as described in Bessonov et al., 2008) were added to a solution of N-phenylsalicylaldimine in methanol. The mixture was stirred for 6 h in an argon flow. Then, the methanol was removed in vacuum and the residue was redissolved in hexane. The hexane solution was filtered and the volatile components were removed in vacuum. The complex was purified by recrystallization from hexane at -10°C. Pale yellow crystals suitable for X-ray analysis were formed in yield of 80%. The melting point of the complex was 147–150°C (154°C from Murray et al., 1973). The product is stable to air and moisture and soluble in most common organic solvents.
H atoms were were refined with fixed individual displacement parameters [U(H) = 1.2 Ueq(C) using a riding model with Caromatic—H = 0.95 Å and Cmethyl—H = 0.98 Å. The phenolic ring and the methyl H atoms are disordered over two equally occupied positions.

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 title compound has molecular structure constructed from neutral molecules (CH3)2Au(C13H10NO). The gold atom in the molecule has a slightly distorted square planar configuration formed by oxygen and nitrogen atoms of salicilaldimine ligand, and two carbon atoms of methyl groups (Fig. 1). In the coordination square, Au—O and Au—N distances differ slightly, and O—Au—N angle is very close to 90°. The values of Au—CH3 bonds are typical for dimethylgold(III) derivatives (Shibata et al., 1990; Bessonov, Baidina et al., 2007). The salicylaldimine fragment is located on a mirror plane, however carbon atoms C5, C6, C7, C8 and C9 are disordered. The planes of salycilaldimine and phenyl ring are nearly perpendicular (the angle is about 91°). In the crystal, molecules are packed in infinite stacks along the monoclinic axis with the shortest Au···Au distance of 4.2106 (4) Å and Au—Au—Au angle of 121.173 (8)° (Fig. 2). The oxygen atom is involved in intermolecular O···H—C interactions with O···C distances of 3.291 (3) Å. The shortest intermolecular H···H distance in the crystal is about 2.5 Å.
