As found by X-ray structure analysis (tBuO)4AlSnCl (1) is monomeric in the crystal and has a central AlO2Sn four-membered ring (Sn -O 2,153(5) Å , Al-O 1,807(7)Å). The corresponding iso-propyl derivative 2 reacts with SnCl2 to yield a coordination polymer (iPrO)4AlSn2Cl3 3 incorporating a new trigonal bipyramidal Sn2Cl3+ cation [angles at tin from 67,18(5) - 83,90(5)°]. 3 reacts with moisture to give the compound [(iPrO)5Cl2Al2]2O2Sn4Cl2 (4) which has a central O2Sn4Cl2-cluster of approximately D2h symmetry with four-coordinate η4-bridging chlorine atoms.
