In the title compound, [PdCl2(C15H11NO3)2]·CHCl3, the PdII atom adopts a slightly distorted square-planar coordination geometry composed of two Cl atoms in cis positions and two C atoms from isocyanophenyl ligands. The molecular conformation is stabilized by
-
stacking interactions [shortest centroid-centroid distance = 3.600 (1) Å] between substituted benzene rings of different ligands. The crystal packing is characterized by C-H
O and C-H
Cl interactions involving the chloroform solvent molecules.
The title compound was synthesized by the addition of 2 equiv of 2-isocyanophenyl-4-methoxybenzoate into a chloroform solution of [PdCl2(MeCN)2]. The solid product was dissolved and recrystallized by slow evaporation from a solution of Et2O/CHCl3 (1:1, v/v).
All H atoms were positioned geometrically and constrained to ride on their parent atoms, with C—H = 0.95 Å and Uiso = 1.2Ueq(C) for aromatic H atoms, with C—H = 1.00 Å and Uiso = 1.2Ueq(C) for methine H atoms, and with C—H = 0.98 Å and Uiso = 1.5Ueq(C) for methyl H atoms. The highest peak is located 1.28 Å from atom Cl6 and the deepest hole is located 0.78 Å from atom Pd1.

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. |

Isocyanides are important organic reagents used in multicomponent reactions such as, e.g., Ugi and Passerini reactions (Banfi & Riva, 2005). Metal complexes of isocyanides could be used as precursors for the generation of coordinated N-heterocyclic carbenes (NHC's) and acyclic diaminocarbenes (ADS's) (Slaughter, 2012). In turn, PdII-NHC and PdII-ADC systems are particularly interesting since they are used as catalysts in a wide range of cross-coupling reactions (Boyarskiy et al., 2012). Recently, it was observed that the coupling of PdII-bound isocyanides and various nucleophiles leads to the formation of cyclic carbenes (Luzyanin et al., 2009b) and ADC complexes (Luzyanin et al., 2009a; Tskhovrebov et al., 2011; Chay et al., 2012), which could not be obtained by the common methods for the generation of metal carbenes. Here we report the structure of a new isocyanide complex that could be used as a starting material for generation of various palladium carbenes.
In the title compound, the isocyanide ligands are mutually in the cis-position (Fig. 1) insofar as the ligated RNC species exhibit higher trans-effect than the chlorides (Davies et al., 1996). The fragments C–N–C–Pd in both complexes are almost linear, viz., the angles N1–C1–Pd1 and N2–C16–Pd1 are 174.2 (2)° and 177.4 (3)°, respectively. The angles C2–N1–C1 and C17–N2–C16 are 174.3 (3)° and 172.0 (3)°, correspondingly. In the isocyanide moieties, the C≡N triple bonds [C1–N1 1.141 (3) Å and C16–N2 1.150 (3) Å] are close to those in some other palladium-isocyanide complexes (Bertani et al., 1991; Bonati & Minghetti, 1970; Luzyanin et al., 2009a,b; Michelin et al., 1988a,b; Orpen et al., 1989; Rourke, 2007). The molecular conformation is stabilized by π-π stacking interactions [shortest centroid-centroid distance = 3.600 (1) Å] between the substituted benzene rings C9–C15 and C17–C22 of different ligands. The crystal packing is characterized by intermolecular C-H···O and C-H···Cl interactions involving the chloroform solvent molecules (Table 1).
