dc.description.abstract | Since Ni and Cd belong to the 3d and 4d series of transition elements respectively, common perception insists that Ni-Se and Cd-Se bond distances in molecular complexes will be quite different. Present work reports the successful synthesis and detailed characterization of cis-configured mononuclear complex [Ni(SeC5H4N)2(dppe)] (1) as well as novel tetranuclear heterometallic Ni-Cd complex [{Ni2(κ2-SeC5H4N)2(µ-OCH3)CdCl}2] (2). Here, the complex [Ni(SeC5H4N)2(dppe)] act as building block for the preparation of complex 2 which has similar Ni-Se and Cd-Se bond distances (within 0.1 Å). The closeness of these bond lengths has facilitated the preparation of NiSe/CdSe heterostructure. The prepared NiSe/CdSe heterostructure has been thoroughly characterized by pXRD, SEM, TEM and EDS, while diffuse reflectance spectroscopy (DRS) was used to evaluate the bandgap of the heterostructure. Detailed structural analysis of molecular assembly further endorses that bond length similarity of Ni-Se and Cd-Se in complex appears as the key factor in getting the heterostructure upon thermolysis of complex. DFT calculations revealed that underlying spin moments of heterometallic system commands the complex to have Ni-Se and Cd-Se bond distances within 0.1 Å range. The magnetic interactions in complex were reaffirmed by weak ferromagnetic ordering observed in superconducting quantum interference device (SQUID) analysis of molecular assembly at lower temperature. It is believed that controlled preparation of NiSe/CdSe heterostructure from novel single source heterometallic precursor reported in the present work will assist the synthesis of functional chalcogenide materials with technological importance. | en_US |
