TLDR
In this paper, the Ni atom is coordinated by four O atoms from two malonate ligands and two water mol-ecules in a distorted octahedral geometry, and two independent Na+ ions are coordinated by five and six O atoms, respectively.Abstract:
In the title compound, Na2[Ni(C3H2O4)2(H2O)2]·2H2O, the Ni atom is coordinated by four O atoms from two malonate ligands and two water molecules in a distorted octahedral geometry. The two independent Na+ ions are coordinated by five and six O atoms, respectively. The crystal structure is stabilized by the three-dimensional hydrogen-bonding network formed by O—H⋯O hydrogen bonds.read more

On enantiomorph‐polarity estimation
TL;DR: In this article, the behaviour of the Rogers's η parameter for enantiomorph-polarity estimation is examined theoretically and experimentally on simulated intensity data for seven well-assorted compounds.
