[BIS(D-ALANINATO)DIAQUA)NICKEL(II) DIHYDRATE: PREPARATION AND CRYSTAL STRUCTURE
Abstract:
<p align="justify"> The title complex of formula [Ni(NH<sub>2</sub>CH<sub>3</sub>CHCOO)<sub>2</sub>(H<sub>2</sub>0)<sub>2</sub>].2H<sub>2</sub>O has been prepared from nickel(II) chloride in an aqueous solution by adding D-alanine and potassium hydroxide. It has beett crystallized from an aqueous solution and its structure was determined by X-ray structure analysis. The nickel(II) atom adopts distorted octahedral coordination geometry with two bidentate alanine molecules and two water molecules. The complex is neutral and dihydrated. The network crystal structure shows hydrogen bonding between water and amide hydrogens within the lattice, and each fragment of the complex contains two water molecules as hydrated water. </p>
