Abstract: The title compound, K₂[Co^II(H₂O)₆]₂[V₁₀O₂₈]·4H₂O, was obtained by reacting CoCl₂ with KVO₃ and it was found to crystallize in the triclinic system in space group P. The VV distances are in the range 3.050  (1)-3.291  (2)  Å; the four types of V-O bond length are in the ranges 1.604  (3)-1.608  (3) (Ot), 1.902  (3)-2.006  (3) (Oc), 1.678  (3)-2.054  (3) (Ob) and 2.105  (3)-2.342  (3)  Å (Oh).
