Coordination Chemistry of the Antimony(III) and Bismuth(III) Cations using Bis(α-iminopyridine) as Ligand

HALDAR, HRITWIK; Yildiz, Cem. B.; MAJUMDAR, MOUMITA (Wiley, 2023-07)

Bis(alpha-iminopyridine) L has been employed as the redox non-innocent Schiff-base ligand to coordinate with cationic antimony(III) and bismuth(III) centers. Mono- and di- cationic compounds: [LSbCl2][CF3SO3] 1, ...
Unravelling the prebiotic origins of the simplest α-ketoacids in cometary ices: a computational investigation

Dash, Soumya Ranjan; Pandya, Rinu; Singh, Geetika; Sharma, Himanshu; Das, Tamal; HALDAR, HRITWIK; HOTHA, SRINIVAS; Vanka, Kumar (Royal Society of Chemistry, 2024-10)

We have employed the ab initio nanoreactor (AINR) and DFT calculations to explore how the soft impact of comets entering early earth's dense atmosphere could induce chemical reactions in trapped interstellar ice components, ...
Tetra-Cationic Distibane Stabilized by Bis(α-iminopyridine) and Its Reactivity

HALDAR, HRITWIK; DAS, SATYABRATA; Wiedemann, Haakon T. A.; Beuthert, Katrin; Kay, Christopher W. M.; Dehnen, Stefanie; Yildiz, Cem B.; MAJUMDAR, MOUMITA (American Chemical Society, 2025-01)

The work establishes the salt of a tetra-cationic distibane, [L2Sb2][CF3SO3]4 = [1]2[OTf]4 (CF3SO3 = OTf), stabilized by a bis(α-iminopyridine) ligand L, defying the Coulombic repulsion. The synthetic approach involved a ...
