reflections included in the refinement = 27 665, s limits = 2s,
Lorentzian polarisation with absorption corrections, restraints
= 10, parameters = 757. Structure solution was achieved by
direct methods, least squares using SHELXTL (Bruker, 2003).
H atoms were constrained to ideal geometry. CCDC reference
