Assembly Elections of India, 2021: Revisiting Assam

In India,  Assembly Elections were held in Assam, West Bengal, Kerela, Tamil Nadu and Puducherry in the first half of 2021. Driving this study is an attempt to analyse the election results of the state of Assam where Bharatiya Janata Party (BJP) and its allies, Mitrajot or National Democratic Alliance (NDA), successfully defeated the Indian National Congress (INC), and its allies, Mahajot (Grand Alliance). Drawing primarily upon secondary data and applying GIS techniques, the study makes a critical analogy of how Mitrajot managed to accomplish victory. &nbsp

1-Benzyl­sulfanyl-2-[(2-chloro­phen­yl)diazen­yl]benzene

The title compound, C19H15ClN2S, a divalent organosulfur compound belonging to the class of ortho-mercaptoazo compounds, is non-ionic in nature. The azo group in the mol­ecule is moved away from the S atom to attain the stable trans-azo configuration. Here the S atom is not electron deficient, so no intra­molecular N⋯S inter­action exists. Due to steric reasons, the mol­ecule is non-planar: the chlorophenyl and benzyl rings are oriented at dihedral angles of 3.21 (8) and 78.18 (5)°, respectively, with respect to the thiophenyl ring. There are no hydrogen bonds and the crystal structure is stabilized by van der Waals inter­actions

Nickel(II), copper(II), cobalt(II), and palladium(II) complexes with a Schiff base: crystal structure, DFT study and copper complex catalyzed aerobic oxidation of alcohol to aldehyde

<div><p>Ni(II), Cu(II), Co(II), and Pd(II) complexes were synthesized with a Schiff base containing thioether with ONS donors chelating to the metal center. The ligand and complexes were characterized by elemental analysis, FT-IR, ¹H-NMR, UV–visible spectroscopy and magnetic studies. The crystal structures of the ligand and its Ni(II) and Pd(II) complexes were determined by single-crystal X-ray diffraction analysis. Structures revealed that the ligand chelated with Ni(II) and Pd(II) center in slightly distorted octahedral and slightly distorted square planar fashion, respectively. DFT studies of the Pd(II) complex revealed that the calculated structural parameters are very close with the experimentally observed data. The Cu(II) complex shows very good catalytic activity toward the conversion of alcohol to aldehyde under aerobic oxidation with ammonium persulfate.</p></div

Pyrenula chlorospila (Nyl.) Arnold (Pyrenulaceae), a new addition to lichen biota of India

Climatic conditions and physical features of the Eastern Himalayan region encompasses a rich diversity of lichen biota. However, the region’s lichens are still far from extensively explored. Here, we study the genus Pyrenula Ach. from the Dhubri district of Assam in North-East India. Twelve species of Pyrenula have been recorded, of which one of the species, P. chlorospila (Nyl.) Arnold, is a newly reported from India. Morphotaxonomic comments on this species, emphasizing its distribution, are provided.
