Comments on the paper: Synthesis growth and characterization of copper mercury thiocyanate crystal [Indian J Pure & App Phys 49 (2011) 340-343]

TL;DR

This paper critiques a previous study on copper mercury thiocyanate, arguing that the reported spectral data and unit cell parameters do not match the claimed compound, questioning its proper identification.

Contribution

It provides a critical analysis of the spectral and structural data, challenging the accuracy of the original compound's characterization.

Findings

Spectral data do not match the proposed compound

Unit cell parameters are inconsistent with the claimed structure

Questions the validity of the original synthesis report

Abstract

The unit cell parameters, infrared and UV-Vis spectral data reported in the paper by Vijayabhaskaran et al (Indian J Pure & App Phys 49 (2011) 340-343) cannot belong to the colourless crystalline compound formulated as copper mercury thiocyanate CuHg(SCN)4 as claimed by the authors.
