- Mr=130.144, orthorhombic, Pbca, Z=8; at 120K a=17.705(8), b=7.349(4), c=7.302(3) Aring, V=950.1(8) Aring 3, Dx=1.820(1) g cm -3; at 295K, a=17.7079(9), b=7.5096(4), c=7.3774(4) Aring, V=981.05(9) Aring 3, Dx=1.7623(2) g cm -3. The crystal structure has been investigated by neutron diffraction at 120K (lambda=0.7228 Aring) and 295K (lambda=1.210 Aring); final R( F2) values are 0.041 (1418 reflections) and 0.065 (1365 reflections), respectively. The short intermolecular O...O hydrogen bond [2.437(1) Aring at 120K] is found to be asymmetrical [O-H 1.167(1), H...O 1.270(1) Aring] even though the bonding situations around the two formate groups are quite similar.
