Upon heating, 1 undergoes a reversible phase transition at around 340/320 K during the first heating/cooling cycle, resulting in rapid thermochromism with a color change from green (stable state) to red (metastable state) within a few seconds. These mixed stacks then combine to form a molecular solid through Coulomb and van der Waals interactions. In this study, we investigated a Ni-dithiolene dianion salt, 1,1'-diheptyl-4,4'-bipyridinium bis(maleonitriledithiolato)nickelate ( 1), and found that its cations and anions stack alternately to form a uniform mixed stack. This led to the diagnosis of Vitamin D3 toxicity.A thermochromic or mechanochromic material can switch between at least two stable states in response to changes in temperature or static pressure/strain. While he did not have any underlying health condition, he was disorientated and confused with very high calcium levels.“It was during investigations we found that he had been loading himself up with Vitamin D supplements,” Dr Suman Lata, director of nephrology at Fortis Hospital in New Delhi’s Shalimar Bagh, told out the toxic load from this patient’s system took several days after he was put on intravenous fluids and medication.The detailed history of the patient revealed that some time back, he was suffering from a prolapsed intervertebral disc for which he had been prescribed Vitamin D and calcium tablets.“He did not follow up with his former doctor but continued to take Vitamin D tablets daily (which otherwise was a weekly dose) for more than six months.
