چکیده
The asymmetric unit of the title compound, [Ni(C(12)H(8)N(2))(3)][Cr(2)O(7)]·4H(2)O, contains one cation, one anion and four water mol-ecules, three of which are disordered over two sites with equal occupancies. In the cation, the metal centre is coordinated by six N atoms from three 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The [Cr(2)O(7)](2-) anion exhibits a staggered conformation. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds and π-π inter-actions, evidenced by short distances of 3.531 (5) Å between the centroids of aromatic rings.

In the title complex, [Ni(C(12)H(8)N(2))(3)](NO(3))(2)·4H(2)O, the Ni(II) ion is octa-hedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds are present between the complex cations, nitrate anions and water mol-ecules. O-H⋯O hydrogen bonds between the uncoord-inated water mol-ecules lead to t...
