Synthesis, X-Ray Crystal Structure, Solid State Electrical and Optical Properties of New Copper(II) Complex with 1,10-Phenanthroline Ligand Saikat Sarkar, Avijit Sarkar, Yildirim Aydogdu, Fethi Dagdelen, Sougata Sarkar, Krishna Chattopadhyay Asian Journal of Chemistry, 2024 A new ionic copper(II) complex of 1,10-phenanthroline was synthesized and structurally characterized by elemental and spectroscopic analyses, molar conductance and magnetic moment measurements. The crystal structure of complex was also investigated through single crystal X-ray diffraction analysis and suggestted a distorted octahedral geometry around copper(II), where one N atom from 1,10-phenanthroline and three O atoms from three H2O molecules occupying the basal plane while another Nphen and one Cl atom remain at the apical positions. Thus, the presence of three coordinated waters and chloride group along with the counter chloride ion and water of crystallization is responsible for extensive hydrogen bonding present in the molecule. Thus, the complex forms a 3D gigantic H-bonded network. The two types of intermolecular O–H···Cl and O–H···O hydrogen bonding play the pivotal role in crystal packing and plausible conductivity mechanism through the π-π interacting supports. The electrical conductivity and optical properties were also measured and the results focus on the semiconducting nature of the complex with optical band gap (Egd) value 1.23 eV.
Cu(II)-Based Nanofibrous Metallogel for Phenoxazinone Synthase-like Activity Sougata Sarkar, Pradip K. Maji, Yuichi Negishi, Soumen Dutta, Tarak N. Das, Rahul Pan, Saikat Sarkar ACS Applied Nano Materials, 2021 Metallogel formation by an individual ligand is well known, but simultaneous need of two ligands in selective metallogelation is relatively less common. In our present study, we have shown that dis...

Synthesis, characterization, and density functional study of some manganese(III) Schiff-base complexes Susobhan Biswas, Tapas Kar, Saikat Sarkar, Kamalendu Dey Journal of Coordination Chemistry, 2012 Some Mn(III) complexes of N,N′-(2-hydroxy)propylenebis(acetylacetoneimine) (abbreviated to H2L1) and N,N′-(2-hydroxy)propylenebis(2-imino-3-oximino)butane (abbreviated to H2L2), [Mn(III)(Lig)(X)] (where Lig stands for the dianion of the Schiff-base ligands and X stands for CH3COO−, Cl−, Br−, I−) were synthesized. The complexes are characterized with the help of elemental analyses, magnetic moments, spectroscopic data (UV-Vis, infrared), and molecular weight determination (measured by Rast's method). The structures of the complexes were obtained using density functional theory (DFT). DFT calculation shows that 1–4 and 8 are trigonal-bipyramidal whereas 5–7 are square-pyramidal.
