Zinc complexes of Ttz(R,Me) with O and S donors reveal differences between Tp and Ttz ligands: acid stability and binding to H or an additional metal (Ttz(R,Me) = tris(3-R-5-methyl-1,2,4-triazolyl)borate; R = Ph, tBu).

 Zinc complexes of Ttz(R,Me) with O and S donors reveal differences
 between Tp and Ttz ligands: acid stability and binding to H or an
 additional metal (Ttz(R,Me) =
 tris(3-R-5-methyl-1,2,4-triazolyl)borate; R = Ph, tBu).
