A series of new iodide heterobimetallic isopropoxides [I2SnAl(OPri)4}2] (1), [I2SnTi(OPri)5}2] (2), [I2SnNb(OPri)6}2] (3), and [I3SnZr(OPri)5(PriOH)}] (4) obtained on reacting SnI4 with stoichiometric amounts of alkali-metal reagents [KAl(OPri)4]n, [KTi(OPri)5]n, [KZr(OPri)5]n, and [KNb(OPri)6]n, respectively, is reported. The monomeric formulation and hexacoordination of tin proposed for 1−4,
