methanol), together with other oily derivatives, difficult to
characterize. Their solid-state structures have been determined using
X-ray diffraction techniques. The first reacts with excess of methanol
to form the second. However, the yields of the latter are always low
irrespective of the amount of methanol used. Experiments showed that
this reaction also occurs on the TLC plates used for the chromatographic
separation of the complexes. This behaviour is discussed.
