Abstract

... 7. (c); H. Li, EA Mintz, XR Bu; Polym. ... intensity data were collected on a Nonius diffractometer using the 2θ scan mode in the range of 3° < 2θ < 150°, ± h, +k, + l, three standard reflections showed no significant variation in intensity; 5637 reflections measured, 4583 unique (R int =0.026 ... The structure was solved by direct methods and subsequent Fourier difference techniques, and refined anisotropically, by fullmatrix least squares, on F 2 (program NRCVAX 14 ). ...
