The discovery of molecular magnet by Bhagawati Charan Guha is not well-discussed in the history of Indian science. On studying a series of inorganic crystals, Guha found some anomalous magnetic behaviour of copper(II) acetate which was not structurally characterized then. After the discovery of the structure, copper(II) acetate appeared as a dimeric dihydrate molecule rather than an inorganic solid. Guha then put a structure-function correlation between the newly discovered structure of copper(II) acetate and its lowtemperature magnetic data. This dimeric copper(II) acetate dihydrate is now regarded as the first reported molecular magnet.

Abstract


The discovery of molecular magnet by Bhagawati Charan Guha is not well-discussed in the history of Indian science. On studying a series of inorganic crystals, Guha found some anomalous magnetic behaviour of copper(II) acetate which was not structurally characterized then. After the discovery of the structure, copper(II) acetate appeared as a dimeric dihydrate molecule rather than an inorganic solid. Guha then put a structure-function correlation between the newly discovered structure of copper(II) acetate and its lowtemperature magnetic data. This dimeric copper(II) acetate dihydrate is now regarded as the first reported molecular magnet.
