Data were corrected for Lorentz j and polarization effects. Data reduction and analysis were carried out with the Oxford Difrraction j(Wrocław) programs. Structure was solved by direct methods using the SHELXS97 program [ 10] andre- j fined using all F2 data, as implemented by the SHELXL97 program [11]. Non-hydrogen atoms were refined with anisotropic displacement parameters. All H atoms were placed at calculated positions and j were treated as rigid groups. Crystallographic data for the structure reported in this paper have been de- i posited with the Cambridge Crystallographic Data Cen trę, CCDC no. 622317.
