摘要：

New tetraamidato ligands with appended urea moieties have the requisite electrochemical and structural properties to stabilize the dioxoosmium(IV) cation through multiple interactions. In the corresponding 1:1 complexes four strong bonds between metal and nitrogen donor and an additional hydrogen bond between each oxo ligand and a C(O)NHR moiety are responsible for the stability. The primary coordination sphere of an osmium complex of this type is shown on the right. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
