    • o) were considered as observed. Solution using direct methods (SHELXTL PLUS), refined (SHELXTL PLUS) to R = 0.0629, Rw = 0.0763. Non‐hydrogen atoms anisotropic, H atoms at calculated positions and refined in groups with common temperature factors; 292 parameters. All calculations were carried out on a Microvax II and a VAX 6000–420[11–13].
