    • 2 with all reflections (SHELXL‐93). The nonhydrogen atoms were refined anisotropically, the H atoms isotropically. Parameters of the weighting scheme: 0.0589, 0.8644; extinction coefficient x = 0.0029(3); wR2 (R1 for 3429 reflections with I>2σI): 0.145 (0.055), 445 refined parameters. All calculations were carried out on a Micro‐VAX II and a DEC 3000‐300X [15–19].
