The title compound, {[Cu(C10H14N4Se)2(H2O)](BF4)2·2C18H15PO·H2O}n, has a polymeric structure where each CuII 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 CuII 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.
