KGaA, Weinheim.As the number of cases of COVID-19 (SARS-CoV-2) rise in the United States (US), the number of severe cases (those requiring ICU admission) rise with it. Initially, the estimate for severe cases was approximated at 5% based on experience from China.1, 2 However, the World Health Organization's (WHO) estimate from China for severe and critical cases is near 20% (Table).3 The primary clinical feature of COVID-19 is pneumonia, the severity of which directs the clinical course; it has been estimated that, of patients admitted to the ICU, up to half may require either invasive or non-invasive ventilatory support.4 This has created an unprecedented situation for emergency and critical care medicine.

It is observed that the minimum energy structure of the Mg2 @C60 system is C2h symmetry. The MgMg bond distance in the Mg2 @C60 system is much shorter than that in the free Mg2 and Mg2 2+ ion. The formation of the endohedral Mg2 @C60 system is thermochemically spontaneous in nature. The natural bond orbital (NBO) analysis showed the presence of an Mg2 2+ fragment with an MgMg bond inside the C60 cage. The electron density descriptors have identified the covalency in the MgMg bond. A non-nuclear attractor (NNA) is present in the middle of the two Mg-atoms. The bonding interaction between the Mg2 and C60 fragments is ionic in nature and the [Mg2 2+ ] and [C60 2- ] represent the bonding pattern in the Mg2 @C60 system. The de
