The aqua-bis(ethylenediamine)-chloro-copper(II) chloride complex, [Cu(en)2(H2O)(Cl)]Cl (1), was synthesized by direct interaction of CuCl2 ×2H2O with pepa (pepa is a polyethylenepolyamine containing ethylenediamine (en)). The crystalline complex 1 was characterized by IR spectra and structurally studied. Crystals of this complex consist of the [Cu(en)2(H2O)(Cl)]+ discrete cations, whose Cu2+ ion is chelated by two en molecules. The Cu(II) coordination polyhedron has the shape of an elongated square bipyramid, in which four nitrogen atoms of the –NH2 groups of en molecules form the base of this bipyramid, and the oxygen atom of the water molecule and Cl– are in its apical positions. |
