Clivagem dos ciclopaladados diméricos [Pd(dmba)(m-X)]2 (dmba = N,N-dimetilbenzilamina; X = Cl, N3, NCO) por tiouréia

μ-Azido-κ2N1:N1-μ-chlorido-bis[(2-chloro-3-dimethylamino-1-phenylprop-1-en-1-yl-κ2C1,N)palladium(II)] chloroform monosolvate

In the binuclear title complex, [Pd₂(C₁₁H₁₃ClN)₂Cl(N₃)]·CHCl₃, each Pd^II 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.

Antitumor and antimycobacterial activities of cyclopalladated complexes: X-ray structure of [Pd(C2,N-dmba)(Br)(tu)] (dmba=N,N-dimethylbenzylamine, tu=thiourea)

The reactions between [Pd(C(2),N-dmba)(micro-X)](2) (dmba=N,N-dimethylbenzylamine; X=Cl, Br) and thiourea (tu) in the 1:2 molar ratio at room temperature resulted in the mononuclear compounds [Pd(C(2),N-dmba)(Cl)(tu)] (1) and [Pd(C(2),N-dmba)(Br)(tu)] (2), which were characterized by elemental analyses and infrared (IR), (1)H- and (13)C{(1)H} NMR spectroscopies. The crystal and molecular structures of 2 were determined by single-crystal X-ray diffraction. In vitro cytotoxicity assays of the compounds 1, 2, tu, dmba and cisplatin were carried out using two murine tumor cell lines, namely mammary adenocarcinoma (LM3) and lung adenocarcinoma (LP07). The compounds 1, 2, tu and dmba were also tested against Mycobacterium tuberculosis and their MIC values were determined.
