Abstract
In multimetal cyanide complexes, more than 30% by weight of the primary particles have a platelet-like habit, i.e. the length and width of the primary particles is at least three times the thickness of the particles.

A multimetal cyanide complex in which more than 30% by weight of the primary particles have a platelet-like habit, i.e. the length and width of the primary particles is at least three times the thickness of the primary particles.
A process for preparing a multimetal cyanide complex in which more than 30% by weight of the primary particles have a platelet-like habit, i.e. the length and width of the primary particles is at least three times the thickness of the primary particles, by combining a metal salt with a cyanometalate compound in the presence of at least one surface-active substance.
