a Borate ester anion. b Guanidinium cation. c H-bond linking (denoted as dashed yellow line) between a and b. d Gd-B framework comprising borate ester anion and guanidinium cation via H-bond linking (highlighted by dashed yellow line, disordered Cl− and guest MeOH molecules are omitted for clarity). The Gd-B framework features a pore size of 4.8 Å that enables the inclusion of MeOH molecules. Grayish blue, light gray, pink, gray, and pale blue balls denote N, H, O, C, and B atoms, respectively.
