Abstract: The title compound, {[Cu(C₁₀H₁₄N₄Se)₂(H₂O)](BF₄)₂·2C₁₈H₁₅PO·H₂O}_n, has a polymeric structure where each Cu^II ion adopts a square-pyramidal coordination constituted by four N atoms of pyrazole moieties in the equatorial plane and an axial O atom of a water molecule. A pair of bis(3,5-dimethyl-1H-pyrazol-4-yl) selenide ligands bridges the Cu^II centres into a chain extending along the c axis. The water molecules, anions and triphenylphosphine oxide molecules are involved in intermolecular hydrogen bonding, which links the chains into a three-dimensional network.
