A chiral chromium complex32was synthesized, and crystals were grown from a solution of the racemate. The crystal structure was chiral with the space group P212121. It can thus be assumed that the crystallization had proceeded by spontaneous resolution, giving rise to a racemic conglomerate. Two ...
space group P212121,怎么理解?甲壳素是生物大分子,长链结构。 The unit cell contains two polymer chains in a 21 helix conformation and in the antiparallel orientation. 注:(1是2的下标) 麻烦大神解释一下 图片2.jpg回复此楼» 猜你喜欢只想摆烂 已经有25人回复 四线城市公办高校无编or二线城市民办...
All of these 12-oxime dehydroabietic acid derivatives crystallize in orthorhombic system, space group P212121. In the structures, rings A and B exhib 三种新颖的dehydroabietate肟衍生物从dehydroabietic酸被综合了,并且他们的晶体结构取决于X-ray晶体技术。 所有这些12肟dehydroabietic酸的衍生物在orthorhombic...

Save time- searching for research chemicals and supplies takes hours. Hours that could be better spent doing what you do best -research. Leave the busy work to us. Save money- don't pay 10 times too much for the same products and unlike most chemical companies we are transparent with our...

The variable-temperature single-crystal X-ray diffraction data suggests that the phase transition was from high crystallographic symmetry with a space group of Pnma to a low-symmetry state with a space group of P212121. That is, Landau symmetry breaking occurred with a pure GPT (mmm–222). ...
