3. Data have not been collected in sufficient way. A rule is that the numerical hkl values in – and + direction for each index should at least reflect the lattice constants. 6. This is neither possible/correct for the methyl-H atoms of 1 and 2 nor for the methanol O-H of 1. For all these H atoms the SHELX commands HFIX 137 (methyl H) and HFIX 147 (the O-H) must be used (without set positions). Also statements concerning the H-refinement procedures are missing (D-H distances, Uiso). 7. Most H atoms are constrained during refinement which is sound. However, it is absolutely unclear and not sound why H7 (for 1) and H2 (for 2) were refined freely. Both refinements resulted in senseless short D-H distances .?Moreover, room-temperature data sets are no good basis for free H-atom refinement. 有大佬帮帮我吗？ 发自小木虫IOS客户端 |
