Crystal structure of potassium borodicitrate (dicitratoborate) K[(C6H6O7)2B]�2H2O

Formation and Structure of Cinchona Alkaloid (Bis-2,3-naphthalenediyl)orthoborate Salts

“…One half of the anion is almost completely flat, whereas the other half is folded: the torsion angle C 4 6 -C 4 7 -C 3 8 -C 3 9 is -2.2(9)° and the five- m em bered ring adopts a flattened envelope con formation with the pseudo-mirror plane passing through the boron atom and the middle of the bond C 38-C 47. The dihedral angle between two aromatic moieties of the anion is 8 8 .8 (2 )°, similar to other organoborate complex anions [17][18][19][20]. The B -O distances are in agreement with those found in other tetrahedral borate structures [e.g.…”

K3B3O4(OH)4·2H2O: A UV Nonlinear Optical Crystal with Isolated [B3O4(OH)4]3– Anion Groups

“…To further understand the structure, we compared the structure with the Pna2 1 phase reported by Zviedre. 20 Our structure possesses an orthorhombic C-centered Bravais lattice with 14 unique atoms in the asymmetric unit while the Pna2 1 phase has an orthorhombic primitive Bravais lattice with 24 unique atoms in the asymmetric unit. K1, B2, O5, O6 in our data are located in 4a Wyckoff positions and the others are all located in 8b Wyckoff positions while all of the atoms in Pna2 1 phase are located in 4a Wyckoff positions.…”

A Systematic Synthetic Study of the Aqueous Chemistry of Binary Boron–Hydroxycarboxylic Acid Systems: Boron Structural Speciation Correlation to the Biotoxicity Profile

“…Each doubly deprotonated glycolic acid ligand is almost planar and the two coordinated ligand planes are almost orthogonal to each other (Figure A). The geometry around boron is distorted tetrahedral and the bite angle, as well as the boron–oxygen distances, is typical, as compared with analogous systems already published in the literature , . The complex assemblies are arranged parallel to the c crystallographic axis, forming chains of independent monoanions.…”
