By using a simple solution chemistry approach with polyvinyprrolidone (PVP) as a capping agent, Mn 2 W(CN) 8 · x H 2 O microcrystals with unique morphologies including rice‐like, rod, octahedron, square platelet, and hollow‐core square platelet have been successfully synthesized. The influence of experimental parameters such as reaction temperature, feed ratio of Mn 2+ to PVP, reaction time, and reactant concentration on the morphology and size of Mn 2 W(CN) 8 · x H 2 O microcrystals were systematically investigated. The reaction temperature proved to be a key factor for morphological evolution of the products. It was found that 20, 55, and 85 °C were key points of morphological transformation. A possible growth mechanism of the Mn 2 W(CN) 8 · x H 2 O microcrystals is proposed.
