Popis: As a proposal for an undergraduate second or third year inorganic laboratory course, the present paper describes the preparation of three representative boron complexes: potassium tetrafluoroborate, pyridoxin boron complex and potassium bis(oxalato)borate. The complexes are characterised by infrared and multinuclear magnetic resonance spectroscopy (¹H, 11B and 19F) where isotopic effects are demonstrated.
