Tin(IV) and organotin(IV) compounds containing hydridotris(3,4,5-trimethyl-1H-pyrazol-1-yl)borate (L(3)), [R(n)SnCl(4-n-1)L(3)] (R = Me, n = 0-2) have been synthesised and studied by NMR (H-1, C-13, Sn-119) spectroscopic techniques. The compounds are not fluxional and contain six-coordinate tin(IV) with a tridentate ligand. X-ray crystal structure of [MeSnCl(2)L(3)] is reported together with that of the parent potassium hydridotris(3,4,5-trimethyl-1H-pyrazol-1-yl)borate, K(C18H28N6B) and comparisons are made.

Abstract
Tin(IV) and organotin(IV) compounds containing hydridotris(3,4,5-trimethyl-1H-pyrazol-1-yl)borate (L(3)), [R(n)SnCl(4-n-1)L(3)] (R = Me, n = 0-2) have been synthesised and studied by NMR (H-1, C-13, Sn-119) spectroscopic techniques. The compounds are not fluxional and contain six-coordinate tin(IV) with a tridentate ligand. X-ray crystal structure of [MeSnCl(2)L(3)] is reported together with that of the parent potassium hydridotris(3,4,5-trimethyl-1H-pyrazol-1-yl)borate, K(C18H28N6B) and comparisons are made.File in questo prodotto:
