In the centrosymmetric title compound, [Cu(C8H7O 2)2(C6H6N2O) 2]·2H2O, the CuII ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methylbenzoate anion, one isonicotinamide ... -
Boric acid complexes with organic biomolecules: Mono-chelate complexes with salicylic and glucuronic acids
Two mono-chelate borate complexes, lithium mono-salicylatoborate and sodium mono-glucuronatoborate, are reported for the first time. The complexes were isolated from aqueous solutions and characterized by FTIR (Fourier ... -
A comparative examination of mono- and bis-chelate salicylatoborate complexes and the crystal structure of layered magnesium bis-salicylatoborate
Complexes of boric acid with sodium- and magnesium-salicylates were prepared and analyzed to examine the structural consequences resulting from the coordination of the salicylate ligand in mono- and bis-chelate modes. The ... -
