The crystal structure of the salt calcium (2R,3R)-tartrate tetrahydrate {systematic name: poly[[diaqua[μ-(2R,3R)-2,3-dihydroxybutanedioato]calcium(II)] dihydrate]}, {[Ca(CHO)(HO)]·2HO}, is reported. The absolute configuration of the crystal was established unambiguously using anomalous dispersion effects in the diffraction patterns. High-quality data also allowed the location and free refinement of all the H atoms, and therefore to a careful analysis of the hydrogen-bond interactions.
报道了四水合（2R，3R）-酒石酸钙盐的晶体结构{系统名称：聚[[二水合[μ-（2R，3R）-2，3-二羟基丁二酸根]钙（II）]二水合物]}，{[Ca(C₄H₄O₆)(H₂O)₂]·2H₂O}。利用衍射图中的反常色散效应明确确定了晶体的绝对构型。高质量的数据还使得所有H原子的位置得以确定并进行自由精修，从而能够仔细分析氢键相互作用。
