SYNTHESIS, CRYSTAL STRUCTURE, SPECTROSCOPIC, LUMINESCENCE STUDIES AND HIRSHFELD SURFACE ANALYSIS OF BLUE LIGHT EMITTING HETEROMETALLIC MNIII-NIII COMPLEX

Abstract

The synthesis, crystal structure, spectroscopic, luminescence properties and Hirshfeld surface analysis of a new heterometallic complex, [Mn(L)(H2O)(CH3CH2OH)]2[Ni(CN)4], (H2L=N,N՛-bis(3,5-di-t-butylsalicylidene)-1,2-propanediamine) was reported. Single crystal diffraction measurements showed that the heterometallic MnIII-NiII complex consists of two [(Mn(L)(H2O)(CH3CH2OH)]+ cations and one [Ni(CN)4 ]2- anion. The Mn1 and Mn2 ions are hexacoordinate by N2O4 donor sets and have a distorted octahedral geometry. The 3-D Hirshfeld surface and 2-D fingerprint plots showed that the main interactions were the H∙∙∙H intermolecular interactions with relative contributions of about 73.8%. According to solid-state luminescence measurements, the new heterometallic MnIII-NiII complex showed weak blue light emission.
