چکیده
In the title complex, [PdBr(C(4)H(3)N(2))(C(18)H(15)P)(2)], the geometry around the Pd(II) atom is distorted square-planar with the Pd(II) atom displaced by 0.0150 (5) Å from the least-squares BrP(2)C plane. Two PPh(3) ligands are in trans positions [P-Pd-P = 176.743 (17)°], while the pyrimidinyl ligand and Br atom are trans to one another [C-Pd-Br = 176.56 (5)°]. Structural parameters from NMR, IR and mass spectra are in agreement with the crystal structure of the title compound.

The title compound, [Pd(C(6)H(4)N(2)S(2))(C(18)H(15)P)(2)], was obtained as a minor product from the reaction of trans-PdCl(2)(PPh(3))(2) with piperazine-1,4-dicarbothioic acid bis-(pyridin-2-yl)amide. The Pd(II) atom displays a slightly distorted square-planar PdP(2)S(2) geometry with a bidentately coordinated pyridin-2-ylcarbonimidodithio-ate ligand and two triphenyl-phosphine mol-ecules, coo...
