Abstract
The infrared spectrum of the title compound, examined in a KBr disc, c ontains two strong overlapping bands in the CN stretching region. In o riented samples of the same material, examined with light traveling al ong the c axis, the sharper of these bands is absent. This is in accor d with a model in which the octahedral ferrocyanide ions are oriented with their individual 3-fold axes parallel to the c axis. The results suggest a general method for determining the orientation of intercalat ed and exchanged species in layered hosts.
