(4,6-Dimethyl-2-sulfanylidenepyrimidin-1-ium) trichlorido(thio­urea-κS)zinc(II)

The title compound, (C₆H₉N₂S)[ZnCl₃{SC(NH₂)₂}], exists as a zincate where the zinc(II) centre is coordinated by three chloride ligands and a thio­urea ligand to form the anion. The organic cation adopts the protonated 4,6-dimethyl-2-sulfanyl­idenepyrimidin-1-ium (L) form of 4,6-dimethyl­pyrimidine-2(1H)-thione. Two short N—H...Cl hydrogen bonds involving the pyrimidine H atoms and the [ZnCl₃L]⁻ anion form a crystallographically centrosymmetric dimeric unit consisting of two anions and two cations. The packing structure is completed by longer-range hydrogen bonds donated by the thio­urea NH₂ groups to chloride ligand hydrogen-bond acceptors.

Poly[di­aqua­[[mu]₄-4-(isonicotinamido)­phthalato]nickel(II)] displaying an sra topology

A 4-(isonicotinamido)­phthalate ligand links Ni^II centres into a three-dimensional structure with sra topology. The structure is stabilized by N-H...O hydrogen bonding between uncoordinated amide groups and extensive O-H...O hydrogen bonding between the coordinated water mol­ecules.
