Single crystals of Bi(C{sub 2}O{sub 4})OH were obtained by the slow diffusion of Bi{sup 3+} cations through silica gel impregnated with oxalic acid. The structure was solved in the Pnma space group with a=6.0853(2) A, b=11.4479(3) A, c=5.9722(2) A, leading to R=0.0188 and wR=0.0190 from 513 unique reflections. The bismuth coordination polyhedron is a BiO{sub 6}E pentagonal bipyramid with the lone pair E sitting at an axial vertex. The opposite axial vertex is occupied by a hydroxyl oxygen atom, which is also an equatorial corner of a neighboring BiO{sub 6}E bipyramid. The sharing of the hydroxyl oxygen atoms build {sub {infinity}}{sup 1}[BiO{sub 5}E] zig-zag chains running down the [100] direction. These chains are aligned in a sheet parallel to the (010) plane and are further connected through oxalate ions to form a three-dimensional arrangement. On heating, Bi(C{sub 2}O{sub 4})OH decomposes to the meta-stable quadratic {beta}-Bi{sub 2}O{sub 3} phase. - Graphical abstract: {sub {infinity}}{sup 1}[BiO{sub 5}E] zig-zag chains running down [100] in Bi(C{sub 2}O{sub 4})OH.
