Abstract
The X-ray structural analysis of the title compound has been determined from diffractometer data and refined by least-squares to R 0·08 for 2211 independent reflexions. Crystals are monoclinic, space-group P21/c, a= 16·401(4), b= 10·856(6), c= 15·072(4)Å,β= 91·07(3)°, Z= 4. In the complex cation the two secondary amine and two imino-donor groups are in trans planar co-ordination. The two asymmetric carbon centres and the two asymmetric nitrogen centres occur in racemic pairs, the configuration of the racemate being (1RS, 3SR, 8RS, 10SR).Keywords
