The syntheses of the alkanolamine N-(CH2CMe2OH)(2)(CMe2CH2OH) (1), of the stannatrane N(CH2CMe2O)(2)(CMe2CH2O)SnO-t-Bu (2), and of the trinuclear tin oxocluster 3 consisting of the two isomers [(mu(3)-O)(O-t-Bu){Sn(OCH2CMe2)(OCMe2CH2)(2)N}(3)] (3a) and [(mu(3)-O)(mu(3)-O-t-Bu){Sn(OCH2CMe2)(OCMe2CH2)(2)N}(3)] (3b) as well as the isolation of a few crystals of the hexanuclear tin oxocluster [LSnOSn(OH)(3)LSnOH](2) [L = N-(CH2CMe2O)(2)(CMe2CH2O)] (4) are reported. The compounds were characterized by H-1, C-13, N-15, and Sn-119 (1-3) nuclear magnetic resonance and infrared spectroscopy, electrospray ionization mass spectrometry, and single-crystal X-ray diffraction analysis (1-4). A graph set analysis was performed for compound 1. The relative energies of 3a and 3b were estimated by density functional theory calculations that show that the energy differences are small.
