Observations on dislocations in manganese(II) formate dihydrate, sucrose, and other crystals of the monoclinic system

Abstract

By etching the cleavage faces of manganese(II) formate dihydrate crystals with ethanol the nature of the dislocations present in this solid have been identified and shown to be almost identical with those that occur in sucrose, which has a similar space-group. The three major types of dislocation so far identified in monoclinic crystals are {h0/}[010], {hk0}[001], and {0k/}[011].
