Abstract

We report the synthesis of two hydrogen-containing perovskite-type bronzes H_0.23WO₃ and H_0.10ReO₃ utilizing an unconventional solid-state synthetic approach, involving the use of the polymer Poly(vinylidene fluoride) (CH₂CF₂)_n. Powder neutron diffraction at ambient temperature shows that H_0.23WO₃ crystallizes in a tetragonal symmetry distortion of the simple perovskite structure (space group P4/nmm), with lattice parameters a = 5.2279(2) Å, and c = 3.8763(1) Å. H_0.10ReO₃, in contrast, crystallizes in a monoclinic distortion of a simple cubic perovskite (space group P2/m), with lattice parameters a = 5.3125(1) Å, b = 5.3155(3) Å, c = 3.7045(3) Å, and γ = 90.43(1)°. Both H_0.23WO₃ and H_0.10ReO₃ exhibit intrinsically diamagnetic behavior, with low temperature paramagnetic upturns and no signs of bulk superconductivity down to 0.35 K.
