Polymorphism of Bis(benzimidazole)bis(thiocyanato-<i>N</i>)cobalt(II) and Its Relevance to Studies of the Chief Color Test for Cocaine

Cobalt(II) thiocyanate-based tests are routinely used to screen cocaine products, with the formation of a blue species interpreted as a positive response. Two popular candidates for the origin of the blue color are an ionic coordination compound, frequently referred to as an ion pair, of the general...
