Methods & Facilities

Synthesis: We are a synthetic inorganic and organometallic chemistry group with particular interests in catalysis and developing renewable energy and energy efficient methods. The research activities in my group involve synthetic inorganic and organometallic chemistry while various spectroscopic characterization, single crystal X-ray diffraction and computational methods are also routinely employed. After the successful synthesis of new ligands, the following studies are carried out:

  • Study of complexation of the new ligands with base transition metals as well as “precious” metals. Complete characterization of new metal complexes with usual spectroscopic methods (IR, UV-Vis, Multinuclear NMR studies, Mass Spectrometry, etc.) and single crystal X-ray diffraction studies.
  • Investigation of reactivity of new metal complexes towards small molecules and exploring possible catalytic applications in suitable reactions.
  • Attempts to identify intermediate structures in the reaction mixture allowing for detailed mechanistic studies are of great interest in our work.

Inert Atmosphere Techniques: Several ligands and complexes prepared in our lab are extremely air and/or moisture sensitive. Therefore, we utilize standard Schlenk techniques during the synthesis and isolation of compounds.

  • Schlenk lines: Our laboratory has four fume hoods equipped with Schlenk-type inert-gas/vacuum lines.
  • Glove box: We have two gloveboxes, a 4-port and a 2-port MBraun UNIlab Pro equipped with freezer, cold-well and vacuum line to carry out reactions and work-up in an inert atmosphere of nitrogen or argon.

 

Spectroscopy: Although multinuclear NMR spectroscopy is the “everyday” method to characterize our new compounds, we also utilize other spectroscopic methods available at the Sophisticated Instrument Center (SIC), IIT Indore for complete characterization of new compounds. The following instruments, available at SIC, are routinely used for our characterization needs;

    • NMR: FT-NMR spectrometer, AVANCE III 400 Ascend, Bruker BioSpin International AG, Switzerland.
    • Mass (LC-MS): SIC is equipped with Bruker Daltonik, Benchtop easy-to-use, High-Performance Electrospray Ionization Quadrupole time-of-flight LC-MS spectrometer.
    • Infrared (FT-IR): Tensor 27, BRUKER (with MIR source, ZnSe beam splitter and DLaTGS detector).
    • UV-Vis: Varian Cary 100 Bio UV-Visible Spectrophotometer.

Single Crystal X-ray Diffraction: Single crystal X-ray diffraction studies are performed in our laboratory in order to gain detailed structural insight for understanding the properties and reactivity behaviour of our newly synthesized compounds. Single Crystal X-ray Diffraction Facility at SIC is equipped with state of the art dual core Agilent Technologies (Oxford Diffraction) Super Nova CCD System.
