The title compound, CHNO, is a commercially available material and can be used as a multidentate ligand. The mol-ecule of the asymmetric unit has an configuration, while the corresponding -configured mol-ecule of the racemic mixture is generated by a crystallographic centre of symmetry. Both hy-droxy groups (the H atom of the oxime group is equally disordered over two positions) are involved in hydrogen bonding, leading to the formation of chains extending parallel to [001].
标题化合物CHNO是一种市售材料,可用作多齿配体。不对称单元的分子具有构型,而外消旋混合物中相应构型的分子由晶体学对称中心产生。两个羟基(肟基的H原子在两个位置上同等无序)都参与氢键形成,导致形成平行于[001]延伸的链。
