Abstract
Two new alkaline metal borates containing 1D {B5}/{B6} oxoboron helical chains, namely Na0.5[B5O8(OH)2]0.5[B5O6(OH)2]0.5·0.5H3O(1) and NaKCs[B6O9(OH)3](2) were synthesized under solvothermal conditions. Compound 1 contains the interesting alternative left- and right-handed helical {[B5O8(OH)2][B5O6(OH)2]}2− ({B5}-1 and {B5}-2) 1D chains and compound 2 possesses the similar [B6O11(OH)3]7−({B6}) chains. Their 1D chains are further assembled into 2D layers and 3D supramolecular frameworks through O-H⋯O hydrogen bonds. In addition, the UV cutoff edge of compounds 1 and 2 is both below 190 nm.
