μ-Azido-κ2 N 1:N 1-μ-chlorido-bis[(2-chloro-3-dimethylamino-1-phenylprop-1-en-1-yl-κ2 C 1,N)palladium(II)] chloroform monosolvate

In the binuclear title complex, [Pd2(C11H13ClN)2Cl(N3)]·CHCl3, each PdII atom has a slightly distorted square-planar geometry being coordinated by a C and an N atom of the 2-chloro-3-dimethylamino-1-phenylpropyl ligand, a bridging Cl atom and an N atom of a bridging end-on azide group. There is a short intramolecular C—H⋯Cl contact in the complex molecule. In the crystal, the chloroform solvent molecule is linked to the complex via a C—H⋯π interaction.

Experimental
The title compound was synthesized from the interaction between the dimer [Pd(DMBA)(µX)] 2 (where X = Cl, N 3 , NCO) and thiourea, being the product of the cleavage reaction. The reaction was performed by mixing a 1:2 stoichiometric amount of[Pd(DMBA)(µN 3 )] 2 and thiourea in chloroform at room temperature with constant stirring during 1 h. After the reaction mixture was left for the solvent to slowly evaporate at room temperature. Large yellow needle-like crystals suitable for X-ray diffraction analysis were obtained.

Refinement
The C-bound H-atoms were included in calculated positions and treated as riding atoms: C-H = 0.93, 0.96 and 0.97 Å, for CH, CH 3 and CH 2 H atoms, respectively, with U iso (H) = k × U eq (C) where k = 1.5 for CH 3 H atoms, and = 1.2 for other H atoms.
