Abstract
- The reaction of o -phenyl-enedi-amine (OPD), sodium naphthalene1,5-di-sulfonate (Na <subscript>2</subscript> NDS) and nickel sulfate in an ethanol-water mixture yielded the title compound, [Ni(OPD) <subscript>2</subscript> (H <subscript>2</subscript> O) <subscript>2</subscript> ]·NDS or [Ni(C <subscript>6</subscript> H <subscript>8</subscript> N <subscript>2</subscript> ) <subscript>2</subscript> (H <subscript>2</subscript> O) <subscript>2</subscript> ](C <subscript>10</subscript> H <subscript>6</subscript> O <subscript>6</subscript> S <subscript>2</subscript> ). This salt consists of a complex [Ni(OPD) <subscript>2</subscript> (H <subscript>2</subscript> O) <subscript>2</subscript> ] <superscript>2+</superscript> cation with two bidentate OPD ligands and trans aqua ligands, and a non-coordinating NDS <superscript>2-</superscript> anion, which is the double-deprotonated form of H <subscript>2</subscript> NDS. The Ni <superscript>II</superscript> atom is situated at a center of inversion and exhibits a slightly tetra-gonally distorted {O <subscript>2</subscript> N <subscript>4</subscript> } octa-hedral coordination environment, with four shorter equatorial Ni-N bonds [2.0775 (17) and 2.0924 (18) Å] and a longer axial Ni-O bond [2.1381 (17) Å]. The OPD ligand is located about an inversion center and is nearly coplanar with the NiN <subscript>4</subscript> plane [dihedral angle 0.95 (9)°]. In the crystal, the cations and anions are connected by charge-assisted inter-molecular N-H⋯O and O-H⋯O hydrogen-bonding inter-actions into the tri-periodic network structure. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (44.1%), O⋯H/H⋯O (34.3%), C⋯H/H⋯C (14.8%) C⋯C (6.5%) (involving the cations) and O⋯H/H⋯O (50%), H⋯H (25%), C⋯H/H⋯C (15.3%), C⋯C (8.2%) (involving the anions) inter-actions.<br /> (© Suyunov et al. 2023.)
