✦ Synopsis

We have determined from X-ray diffraction that lead stearate, which like many hydrocarbon compounds does not form good crystals in bulk, can be grown epituxiully on mica using the Langmuir-Blodgett technique. The strong alternation in intensities of the (1 II) peaks cannot be explained by considering the lead ions only, and imply that the hydrocarbon chains do not close-pack into a triangular array but reproduce the in-plane structure of the lead ions.
