This average structure (Av) exhibited unusully large anisotropic displacement parameters. Generation of a fourier difference map from this data dataset with the model for DHCBZ form II, which has almost identical unit cell dimentions, produced peaks of residual electron density in the CBZ moiety position. The final disorded model was obtained by the refinement of the DHCBZ form II model and the averaged structure model Av as a 50:50 system this resulted in the average structure model Av refining to the CBZ molecular structure as defined by a C7-C8 bond lenght of 1.36(1) with the corrisponding bond in the DHCBZ moiety equal to 1.52(1). A free refinement of the CBZ to DHCBZ ratio gave 0.48 so the ratio was fixed to be 0.5 in the final refinement. When either the CBZ moiety or the DHCBZ moiety was removed from the disordered structure the remaining moiety refined to the average structure Av coordinates. but when both moietys were present in the model the refinement remained stable. Constraints have been used to fix the hydrogen atoms to geometrically sencible positions and to reduce the number of parameters required to define the aromatic rings. Without these constraints a chemically resonable refinable model was obtained but the data to parameter ratio was low. Refinement of F^2^ against ALL reflections. 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. ; _refine_ls_structure_factor_coef Fsqd _refine_ls_matrix_type full _refine_ls_weighting_scheme calc _refine_ls_weighting_details 'calc w=1/[\s^2^(Fo^2^)+(0.0844P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' _atom_sites_solution_primary direct _atom_sites_solution_secondary difmap _atom_sites_solution_hydrogens geom _refine_ls_hydrogen_treatment constr _refine_ls_extinction_method none _refine_ls_extinction_coef ?
