title: Diaquabis(1,3-propanediamine-kappa(2)N,N')nickel(II) bis(sulfanilate).
abstract: The title compound, [Ni(C(3)H(10)N(2))(2)(H(2)O)(2)](C(6)H(6)NO(3)S)(2), contains alternating layers of sulfanilate anions and diaquabis(1,3-propanediamine)nickel(II) cations. The Ni atom lies on an inversion centre and is hexacoordinated by the 1,3-propanediamine ligands, which function as N,N'-bidentate ligands, and the water molecules, which are in a trans arrangement. The sulfanilate anions are arranged in layers, with the sulfonate and amine groups directed towards opposite sides of the layer. The structure is stabilized by a network of hydrogen bonding between the O and N atoms of the sulfanilate anions, the water molecules, and the N atoms of the 1,3-propanediamine ligands.
