摘要：
The reaction of[Os(C6H5)Cl(CO)(PPh3)(2)] with Na[HB(mt)(3)] (mt = methimazolyl) results in benzene elimination and the formation of the first osmaboratrane [B(mt)(3)Os(CO)(PPh3)](Os-->B), the crystal structure of which reveals a somewhat long transannular dative bond between osmium(O) and boron(III). has now included ruthenium examples. Furthermore, structural data are also available for a range of base-stabilized osmium borylene complexes.(9) Thus the wealth of structural data for 2c-2e Os-B bonding provides a suitable basis for interpreting the structural features.(10).
