Structural correlations of organooxotin compounds

A review of the basic structural features of organooxotin cluster chemistry is followed by a presentation of more recent work that illustrates interre lationships apparent on examining other chemistries that exhibit similar st ructural types. For examples, ladders, partial cubes, cubes, and double cub es are now more extensively known that incorporate a mixture of elements ot her than tin. Some compositions of oganotin clusters that combine different elements are the ladder form, [Fe-6(mu(3)-S)(4)(mu(2)-SR)(4)] core, the cu be forms, [n-BuSn(O)O2AsMe2](4), [Mo-3(SnCl3)Se-4(NCS)(9)](6-). the butterf ly compounds, [n-BuSn(OH)-(O2AsMe2)OP(O)Me-2](2) and [n-BuSn(OH)(O2AsMe2)(2 )](2) and the double cubes, [{n-BuSn(S)O2P(p-ClC6H4)(2)}(3)O](2)Sn, [{(H2O) (9)Mo3S4} Sn](8+), and [Mo6AsS8(H2O)(18)](8+). Also of interest are double cubanes with sulfur or oxygen bridges, e.g., [(Fe4S4Cl3)(2)S](4-) and adama ntyl derivatives, e.g., (t-Ru)(4)Ge4S6 and [Fe-4(SPh)(10)](2-). By taking a dvantage of the insight gained from such comparisons, synthetic procedures may reveal themselves in not only extending the chemistry of organotin comp ounds but that of other chemistries based on related clusters.
