    Replacing symmetry operators
        '+x,  +y,  +z'
        '-x,  +y,  -z'
        '-x,  -y,  -z'
        '+x,  -y,  +z'
    with
        '-x+1/2,-y+1/2,-z'
        '-x+1/2,y+1/2,-z+1/2'
        'x+1/2,-y+1/2,z+1/2'
        'x+1/2,y+1/2,z'
    because:

    a) Updated list of symmetry operators constitute full set of
       operators of 'C 1 2/c 1' symmetry space group;

    b) Large crystal voids (up to 6.57 angstroms in diameter) have
       disappeared.
