Description
Summary:The crystal structures of (SP‐4‐4)‐[rac‐2‐(1‐aminoethyl)phenyl‐κ2C1,N]chlorido(pyridine‐κN)palladium(II), [Pd(C8H10N)Cl(C5H5N)], (I), (SP‐4‐4)‐[rac‐2‐(1‐aminoethyl)phenyl‐κ2C1,N]bromido(pyridine‐κN)palladium(II), [PdBr(C8H10N)(C5H5N)], (II), (SP‐4‐4)‐[rac‐2‐(1‐aminoethyl)‐5‐bromophenyl‐κ2C1,N]bromido(4‐methylpyridine‐κN)palladium(II), [PdBr(C8H9BrN)(C6H7N)], (III), and (SP‐4‐4)‐[rac‐2‐(1‐aminoethyl)‐5‐bromophenyl‐κ2C1,N]iodido(4‐methylpyridine‐κN)palladium(II), [Pd(C8H9BrN)I(C6H7N)], (IV), are reported. The latter is the first iodide complex in this class of compounds. All four complexes crystallize in the same space group, viz.I41/a, with very similar lattice parameters a and more flexible lattice parameters c. Their packing corresponds to that of their enantiomerically pure congeners, which crystallize in the t2 subgroup I41.
