The interplays between crystal structures and physical properties in BiCoO3, PbVO3 and BiNiO3 are investigated. It is found that the t2g1 and t2g4eg2 electronic configurations of V4+ and Co3+ ions are the origin of the large tetragonal distortions in BiCoO3 and PbVO3. High pressure neutron diffraction measurements and Bond valence sum calculations on BiNiO3 with unusual oxidation state of Bi3+0.5Bi5+0.5Ni2+O3 show that the pressure-induced melting of the charge disproportionated state leads to a simultaneous charge transfer from Ni to Bi, so that the high pressure phase is metallic Bi3+Ni3+O3.
