title: catena-Poly[[[aqua-copper(II)]bis-[μ-bis(3,5-dimethyl-1H-pyrazol-4-yl) selenide]] bis-(tetra-fluorido-borate) bis-(triphenyl-phosphine oxide) monohydrate].
abstract: The title compound, {[Cu(C(10)H(14)N(4)Se)(2)(H(2)O)](BF(4))(2)·2C(18)H(15)PO·H(2)O}(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 mol-ecule. 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 mol-ecules, anions and triphenyl-phosphine oxide mol-ecules are involved in inter-molecular hydrogen bonding, which links the chains into a three-dimensional network.
