The infrared, ultraviolet, H¹ and B¹¹ nuclear magnetic resonance spectra, and polarographic behavior of a series of R₂B complexes possessing tetrahedral geometry indicate that they and similar derivatives can serve as excellent models with which to study chelate characteristics. The R₂B moiety functions as a pseudo-metal ion or atom which permits alteration of total and effective charge without variation in size of the chelate ring and permits placement and surveying of probes to study the electron distribution in the chelates.
