trans-Diaqua­bis­(L-phenyl­alaninato-κ²N,O)nickel(II)

In the title compound, [Ni(C₉H₁₀NO₂)₂(H₂O)₂], the coordination geometry around the Ni^II ion can be described as distorted octa­hedral, with two N atoms and two O atoms from phenyl­alaninate ligands in the basal plane and two aqua O atoms at the axial sites. The crystal packing is stabilized by inter­molecular O—H...O and N—H...O hydrogen bonds.

N′-[(E)-2-Hy­droxy-5-iodo­benzyl­idene]-4-methyl­benzene­sulfono­hydrazide

In the title mol­ecule, C₁₄H₁₃IN₂O₃S, the dihedral angle between the planes of the benzene and toluene rings is 84.3 (3)°. The mol­ecule displays a trans conformation with respect to the C=N bond. There is an intra­molecular O—H...N hydrogen bond with the azomethine N atom as acceptor. In the crystal, N—H...O hydrogen bonds connect the mol­ecules into chains running along the b axis.
