Tin(II) Poly(1-pyrazolyl)borates
Abstract
Ever since their first preparation poly(1-pyrazolyl)borates, M((pz)( 4-n)BR(n)) (M = alkali metal, Hpz = pyrazole or C-substituted derivative thereof, R = non-coordinating substituent, n= 0,1,2), have found extensive use as chelating ligands in transition metal chemistry. However, studies of the poly(1-pyrazolyl)borate chemistry of main group elements have been rather limited. Only most recently have some characterized poly(1-pyrazolyl)borates of main group (other than alkali and alkaline earth) metals become available. The data include four (somewhat contradictory) reports on tin(IV)3-6 and one on tin(II) derivatives; silicon or germanium poly(1-pyrazolyl)borates have not yet been reported. In an extension of recent studies on the interaction of boron compounds with poly(1-pyrazolyl)borates, the synthesis and characterization of other main group element derivatives of the latter is currently being investigated. The present report describes a study of a series of Sn(II) poly(1- pyrazolyl)borates.
