Abstract

The Squarate complex of Ni(II) with 4, 4-bipyridine compound and [Ni(C4H2O4)2(C10H8N2)2]+2.2Cl-formula was synthesized by soft chemistry, using co-precipitation method. The structure was characterized using infrared spectroscopy for main functional groups confirmation and powder XRD witch show that it crystallize in the monoclinic system, with cell lattice parameters a=9.9674 Å, b=10.538, c=18.7066 Å, V=1940.83 Å3. The structure is based on SBU of NiO2N2 lied to organic entities. The nickel (II) is tetracoordinated with the two donor atoms of 4, 4 bipyridine and two oxygen atoms of the squarate, building a distorted tetraedral around the metal ion.
