Unusual coordination of tetrylenes to molybdenum carbonyl fragments.
Reactions of the tetrylenes Ge(SAr(Me6))2 (1) (Ar(Me6) = C6H3-2,6(C6H2-2,4,6-Me3)2), and Sn(SAr(Me6))2 (2) with (Mo(CO)4(NBD) (NBD = bicyclo[2.2.1]hepta-2,5-diene) gave three new, unusual complexes [Mo(THF)(CO)3{Ge(SAr(Me6))2}] (3), [Mo(THF)(CO)3{Ge(SAr(Me6))2}] (4) and [Mo(CO)4{Sn(SAr(Me6))2}] (5) which display no significant Ge/Sn-Mo bonding. Instead the ligands are coordinated to molybdenum in a bidentate fashion via the thiolato sulfurs.
