Definition of parameters defining the structural distortions of the MIL-53 structure: (a) hinge angle of carboxylate link to inorganic chain ([alpha]), (b) carboxylate O-C-C-C dihedral angle ([beta]), (c) intrachain M-O-M angle ([gamma]) and (d) dimensions of the projection of the diamond-shaped channels. Crystal data were taken from the structure of Co(BDC)(3-Br-PNO): cyan atoms are Co, red O, large grey C and small grey H.  [article HTML]
