Abstract
In the title compound, [Ni(C13H17NO3)(C12H8N2)(H2O)]·5H2O, the Ni(II) atom is in a distorted octa-hedral coordination environment provided by the two N atoms of one bidentate phenanthroline ligand and two O atoms and one N atom from a tridentate 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noic acid (HAMA) ligand and one water mol-ecule. The complex was prepared by the reaction of nickel(II) nitrate with HAMA in the presence of 1,10-phenanthroline in a 1:1:1 ratio. In the crystal, the complex mol-ecules and solvate water mol-ecules are associated via O-H⋯O hydrogen bonds into a three-dimensional network.

Summary
Metal complexes of 1,10-phenanthroline (phen) and its derivatives are of increasing interest because of their versatile roles in many fields such as analytical chemistry 1,10-Phenanthroline is a chelating bidentate ligand with notable coordination ability for transition metal cations. It is widely used in coordination chemistry, in particular, for the preparation of mixed-ligand complexes (Fritsky et al, 2004; Kanderal et al, 2005), and in the synthesis of polynuclear complexes and coordination polymers in order to control nuclearity and dimensionality by blocking a certain number of vacant sites in the coordination sphere of a metal ion (Fritsky et al, 2006; Penkova et al, 2010). Over the last few decades, the complex formation of transition metal ions with amino acids has been studied extensively (Auclair et al, 1984). With the discovery of the biological importance of nickel, it is essential to study its complex formation with amino acids in order to understand more about the functions of their complexes
