Abstract  

Three isomorphous series of new compounds are reported: complexes [M(DBM)2Q2] and [M(DBM)2Iq2] (M = M(II) = Co, Ni, Zn, Cd; DBM is C6H5COCHCOC6H5−) and inclusion compounds [M(DBM)2Q2]*Q (M = Co, Zn, Cd). All the compounds comprise a trans configured octahedral complex molecule. Inclusion compounds of modified Zn and Cd DBM complexes are reported for the first time and their inclusion ability is attributed to the trans isomeric state induced by the bulky Q or Iq ligand. The TG measurements indicate the following order of thermal stability of the complexes defined by the strength of the metal–ligand bonds: Ni > Co > Cd > Zn. The inclusion compounds do not follow this trend.
