Abstract
As found by X-ray structure analysis (tBuO)(4)AlSnCl (1) is monomeric in the crystal and has a central AlO2Sn four-membered ring (Sn-O 2,153 (5)Angstrom, Al-O 1,807(7)Angstrom). The corresponding iso-propyl deri vative 2 reacts with SnCl2 to yield a coordination polymer (iPrO)(4)Al Sn2Cl3 3 incorporating a new trigonal bipyramidal Sn2Cl3+ cation [angl es at tin from 67,18(5)-83,90(5)degrees]. 3 reacts with moisture to gi ve the compound [(iPrO)(5)Cl2Al2]2O2Sn4Cl2 (4) which has a central O2S n4Cl2-cluster of approximately D-2h symmetry with four-coordinate eta( 4)-bridging chlorine atoms.
