• A new potassium lithium double salt of decavanadate, K4Li2[V10O28]·10H2O (1) has been synthesized and characterized. 1 crystallizes in the triclinic system, and features an unusual (6,8)‐connected network with the K4O32 clusters, Li2O10 clusters and V10O28 clusters. The K4O32 clusters and Li2O10 clusters share an edge and a triangle plane to form an infinite rod‐shaped chain. The chains are further interlinked by V10O28 clusters to generate the final 3D framework. UV‐Vis spectrum, fluorescent spectrum and cyclic voltammetry curves have been studied. We synthesized a new potassium lithium double salt of decavanadate, K4Li2[V10O28]·10H2O (1). 1 presents a 3D network with unique (6,8)‐connected (32.410.52.6)(34.412.58.64) topology. UV‐vis spectrum of 1 reveals a significant broad peak between 230 and 370 nm and solid‐state fluorescent spectrum displays a broad fluorescent emission band from 440 to 560 nm upon photo‐excitation at 280 nm. Cyclic voltammetry curves indicated three redox processes.
