All hydrogen atoms were located in a difference Fourier map and their 
coordinates and isotropic displacement parameters subsequently refined. C-H 
bond lengths were restrained to 1.00(4) \%A, C-C-H and H-C-H angles to 
109(2)\% and similarity restraints applied to the displacement parameters 
of the H atoms and their parent C atoms.
