Abstract: | The 4,5-bis(diphenylphosphoranyl)-1,2,3-triazole 4,5-(P(E)Ph2)2tz] derivatives of indium {kappa3-N,N',E-4,5-(P(E)Ph2)2(mu-tz)]InMe2}2 (E = O2, S3, Se4) were prepared in good yield. In addition, compound 5 (E = O, E' = Se) was obtained from 4 through the replacement of a selenium atom in the P-Se(In) moiety by an oxygen atom, giving the mixed-chalcogen complex. The crystal structures of 2 and 5 exhibit a central C4In2N6O2P4core with an almost planar arrangement (mean deviation = 0.019 and 0.042 A for 2 and 0.100 A for 5), while the C4In2N6S2P4 core in 3 is nonplanar (mean deviation = 0.223 A). |
