Crystal Structure of Copper Butyrate Monohydrate

Abstract

VERY few soaps or other similar substances have been examined by means of the X-ray single-crystal technique because of the difficulty of obtaining crystals which are large enough, and particularly crystals which are thick enough. Consequently, there are few data on the unit cell dimensions. Copper butyrate, however, when crystallized by allowing an acetone solution to evaporate at room temperature, gives unusually large and comparatively thick crystals in the form of six-sided plates frequently twinned on the large face. They are of a deep green colour, and on exposure to the air for a day or so the faces become dull, the crystals ultimately disintegrating.
