Author Response: Parameter settings for data collection were less than required for a hemisphere in two theta. Hence, data fraction at 50 degrees is two theta is 96 percent rather than 100 percent. The data fraction at 55 degrees in two theta is 88 percent. The uniqueness of this structure may warrant consideration for publication of this structue eventhough the data collection is less than 100 percent.

Special details

Experimental. A crystal of approximately 0.40 x 0.40 x 0.50 mm³ on an edge was handled under a nitrogen atomosphere and mounted on a glass fiber with Paratone-N oil and then cooled to 198 K. The data were collected on a Siemens Bruker 1 K P4/CCD diffractometer with Mo radiation (Bruker,2001). The strucure was solved by direct methods and completed from subsequent difference Fourier syntheses. Diffraction symmetry indiated a triclinic crystal system and the solution successfully solved in P-1 space group. All non-hydrogen atoms were refined with anisotropic thermal parameters.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
