Pseudosymmetry in a cyclopalladated compound.

The enantiomerically pure title complex, [SP-4-4]-(R)-[2-(1-aminoethyl)phenyl-κ(2)C(1),N]chlorido(quinoline-κN)palladium(II) acetone hemisolvate, [Pd(C(8)H(10)N)Cl(C(9)H(7)N)]·0.5C(3)H(6)O, crystallizes with four molecules of the organopalladium complex and two molecules of acetone in the asymmetric unit. This corresponds to a discrete hydrogen-bonded aggregate and to the content of the unit cell in the space group P1. Pronounced pseudo-inversion symmetry relates pairs of these objects in the asymmetric unit.
