Benzene and borazine, so different, yet so similar: insight from experimental charge density analysis
MR Merino-García, LA Soriano-Agueda… - Inorganic …, 2022 - ACS Publications
Although benzene and borazine are isoelectronic and isostructural, they have very different
electronic structures, mainly due to the polar nature of the B–N bond. Herein, we present an …
