The new {[Ni(phen)(3)][Ni(dipic)(2)]}(2)center dot 17H(2)O (1) (phen = 1,10-phenanthroline, dipic = dipicolinate)) has been prepared and characterized by elemental analysis, IR, UV-Vis, magnetic measurement and single crystal X-ray diffraction. The complex consists of two tris(1,10-phenanthroline) nickel(II) cations, two bis(dipicolinato) nickelate(II) anions and seventeen uncoordinated water molecules. The Ni(II) complex crystallizes in the triclinic space group P-1. The complex consisting of cation has distorted octahedral coordination by three bidentate phen ligands. In the complex anion, each dipic ligand simultaneously exhibits tridentate coordination modes through N atom of pyridine ring and oxygen atoms of the carboxylate groups. The crystal packing of 1 is a composite of intermolecular hydrogen bonding, pi-pi and C-H center dot center dot center dot pi interactions. The complex has also been investigated in terms of biological activity and it showed high activity against S. aureus from Gram positive bacteria and C. albicans from yeast tested.
