Hybrid recoil mass analyzer (HYRA) is a unique, dual-mode spectrometer designed to carry out nuclear reaction and structure studies in heavy and medium-mass nuclei using gas-filled and vacuum modes, respectively and has the potential to address newer domains in nuclear physics accessible using high energy, heavy-ion beams from superconducting LINAC accelerator (being commissioned) and ECR-based high current injector system (planned) at IUAC. The first stage of HYRA is operational and initial experiments have been carried out using gas-filled mode for the detection of heavy evaporation residues and heavy quasielastic recoils in the direction of primary beam. Excellent primary beam rejection and transmission efficiency (comparable with other gas-filled separators) have been achieved using a smaller focal plane detection system. There are plans to couple HYRA to other detector arrays such as Indian national gamma array (INGA) and 4π spin spectrometer for ER tagged spectroscopic/spin distribution studies and for focal plane decay measurements.

The self-assembly of [Co(MeTPyA)(CH 3 COO)]-PF 6 (1) and [Fe(bbp)(CN) 3 ] 2− affords a cyanido-bridged squareshaped {Fe 2 Co 2 } tetranuclear complex, [{Co(MeTPyA)(μ 2 -NC) 2 Fe(bbp)(CN)} 2 ]•3H 2 O (2; MeTPyA = tris((3,5-dimethylpyrazol-1-yl)methyl)amine and H 2 bbp = bis(2-benzimidazolyl)pyridine). The possibility of inducing an intramolecular electron transfer coupled spin transition in 2 by employing protonation as an external stimulant is explored. UV−visible spectrophotometric measurements, electrochemical and 1 H NMR studies establish that a reversible intramolecular electron transfer coupled spin transition can be triggered in 2 upon addition of either acid or base.

A highly symmetric cyanido bridged tetranuclear square shaped [NiII2FeIII2] aggregate exhibits protonation induced intra-molecular electron transfer in solution and switching between [NiII2FeIII2] and [NiIII2FeII2] states.

Role of structural distortion on the uniaxial magnetic anisotropy of pentagonal bipyramidal Ni(ii) complexes is explored. A simple strategy to enhance the uniaxial magnetic anisotropy in pentagonal bipyramidal Ni(ii) complexes is proposed.

A water processable cyanido bridged extended chiral heterobimetallic Co(II)-Fe(III) network is assembled. The unusual water processability of the coordination polymer originate from dangling hydrophilic substituents. The present approach offers a...
