N-Benzoyl­thio­semicarbazide

The title compound, C₈H₉N₃OS, crystallizes in a triclinic unit cell, with two crystallographically independent mol­ecules in the asymmetric unit. It has a two-dimensional layer structure with intermolecular hydrogen bonding.

Diaqua­bis(D-valinato-κ²N,O)nickel(II)

In the title complex, diaqua­bis(2-amino-3-methyl­butyrato-κ²N,O)nickel(II), [Ni(C₅H₁₀NO₂)₂(H₂O)₂], the Ni^II atom (site symmetry 2) is octa­hedrally coordinated by two N,O-bidenate valinate ions and two water mol­ecules. A network of inter­molecular hydrogen bonds links the complex mol­ecules into a two-dimensional network.
