“One Stone Two Birds” Design of Borates Featuring Edge-Sharing [BO4] and Different B-O Configuration in One Structure Utilizing Covalent Tetrahedra

Two borates with ES-[BO 4 ] were created. KABO is the first borate with ES-[BO 4 ] and two distinct dimensional B–O configurations ([B 6 O 12 ] and ). KAMBO is a rare borate contains ES-[BO 4 ] and two isolated B–O groups ([B 6 O 12 ] and [B 3 O 6 ]).
