The weighted R-factor wR and goodness of fit S are based on F^2^, conventional R-factors R are based on F, with F set to zero for negative F^2^. The threshold expression of F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F^2^ are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. Due to the data being collected at room temperature, and the common occurrence of water molecules rotating and moving about their positions, it is difficult to locate the hydrogens on the water molecules accurately, particularly for disordered molecules. As a result, the hydrogen atoms of the water molecules, O(1) and O(2), were not located. The considerable disorder of O(2), shown by the large values of its anisotropic displacement thermal parameters, was modelled in two ways in alternative final refinements: 1) by setting the occupancies of the positions of this water molecule to 0.5 (since an occupancy close to this value emerged for O(2) from a previous refinement); and 2) by setting the occupancies to 0.25 (since O(2) is close to a four-fold rotation axis and belongs to a cluster of four water molecules). The R factors and parameter errors were considerably better with the occupancies of 0.5. The structure contains solvent accessible voids of 76.00 A3 at 0, 0, 0 and 1/2, 1/2, 1/2, which was investigated with the use of SQUEEZE implemented in PLATON. The results of the investigation were negative.
