The tran-bis(ethylenediamine)bis(saccharinato)Zinc(II), [Zn(sac)(2)(en)(2)] (ZSED), (en: ethylenediamine and sac: saccharinate) complex has been synthesized and its crystal structure has been determined by X-ray diffraction analysis. The compound crystallizes in space group P2(1)/c. The Zn(II) ion is hexa-coordinated by four nitrogens of two bidentate en ligands composing the basal plane and two nitrogen atoms from the monodentate two sac ligands (N-bonded) occuping the axial sites, adopting an elongated octahedral sphere. Both en and sac ligands occupy the trans positions of the coordination octahedron. The Zn(II) ion in title compound sits on a inversion centre and is octahedrally coordinated two bidentate en (ethylenediamine) and two sac (saccharinate) (N-bonded) ligands. The magnetic environments of Cu(2+) doped [Zn(sac)(2)(en)(2)] complex have been identified by electron paramagnetic resonance (EPR) technique. Cu(2+) doped ZSED single crystals have been studied at room temperature in three mutually perpendicular planes. The calculated results of the Cu(2+) doped ZSED indicate that Cu(2+) ion contains two magnetically inequivalent Cu(2+) sites in distinct orientations occupying substitutional positions in the host lattice and show very high angular dependence.
