we also calculated the formation enthalpy (energy cost) of the chemical reaction N(CH3)4I + SnI2 → N(CH3)4SnI3in the pressure range of 0–6 GPa. The calculated energy costs for 3D-cubic N(CH3)4SnI3are all negative (see Supplementary Fig.3), which means that 3D...
The findings identify the close connections between the initial and final orbital hybridizations, as well as prominent optical excitations. Based on the computational predictions, It is believed that lead-free materials such as CH3NH3SnI3 and CH(NH2)(2)SnI3 are promising candidates for photovoltaic...
Draw the Lewis structure of (CH3)2NN and show the electronic configuration of the ground state of each N atom. (b) What is the coordination number and hybridization of each N atom. (c) What is the CNN bond angle? (d) ...
