通过溶液和退火制备了Co（NCS）x（NCSe）2-x（吡啶）4的混晶[Co（NCS）x（NCSe）2-x（吡啶）2]n。随着硒代氰酸盐含量的增加，磁交换常数和临界温度（居里温度）的增加被观察到，这提供了一个合理的路线来控制这些参数的细节，而不改变金属阳离子。
Mixed crystals with the composition [Co(NCS)x(NCSe)2-x(pyridine)2]n were prepared from solution and by annealing of Co(NCS)x(NCSe)2-x(pyridine)4. With increasing selenocyanate content, an increase of the magnetic exchange constant and of the critical temperature (Curie temperature) is observed, which offers a rational route to control these parameters in detail, without changing the metal cations.
