Notes:
A New Determination of the Conformation of the Lactonering in the Crystal Structure of Strophanthidin C23H32O6 · 1/2 H2OBy partial difference-Fourier-synthesis a fixed conformation of the lactone ring of the molecule B was established and geometrical parameters were determined. The reason for the occurrence of two symmetrical independent molecules was interpreted by insertion of one water molecule in the crystal structure and by different conformations of both lactone rings. Another H-bridges-system in the crystal structure was deduced.
