Data sets were corrected for Lorentz and polarization effects and for the effects of absorption using the program Scalepack [19]. Structures were solved using the direct methods option of SHELXS-97 [20] and developed using conventional alternating cycles of least squares refinement and difference Foürier synthesis (SHELXL-97 [20]) with the aid of RES2INS [21]. All non-hydrogen atoms were refined anisotropically, whilst hydrogen atoms were fixed in idealized positions and allowed to ride. Hydrogen atom thermal parameters were tied to those of the atom to which they were attached. In the case of 2 unresolved, incommensurate crystal twinning was responsible for the relatively poor overall refinement.
