Abstract: | Substances of the types MH4ntmp, Mg3[M(Hntmp)]2, M2H2ntmp and Mg[M2(Hntmp)]2, where M = Co, Ni, Cu, Zn and H6ntmp = N[CH2PO(OH)2]3 were prepared. The sodium and cesium salts of the [Co(Hntmp)]3− complexes were also prepared. The IR and electronic spectra and the experimental magnetic susceptibilities indicate that these are high-spin complexes. The coordination surroundings of the central atom consist of a highly distorted octahedron of the ligand oxygen atoms. The nitrogen atom is not coordinated to the central atom. |
