Popis: The complexes [HB(3-Bu t -5-Mepz) 3 ] SnCl and [HB(3-Bu t pz) 3 ]CdCl(pz=pyrazolyl ring) have been prepared and their solid-state structures determined ciystallographically. The two structures allow a determination of the impact of the lone pair on ligand geometry and on the metal-donor atom distances for two metals with equivalent ionic radii. The geometry about tin in [HB(3-Bu t -5-Mepz) 3 ] SnCl is best described as a distorted trigonal bipyramid with the chloride ligand in an axial site and the tin lone pair occupying an equatorial position
