Abstract: We report the synthesis of two hydrogen-containing perovskite-type bronzes H0.23WO3 and H0.10ReO3 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 H0.23WO3 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. H0.10ReO3, 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 H0.23WO3 and H0.10ReO3 exhibit intrinsically diamagnetic behavior, with low temperature paramagnetic upturns and no signs of bulk superconductivity down to 0.35 ​K.
