The carbonyl donor 2,6-dimethyl-4H-pyran-4-one (DMP) reacts with zinc and cadmium dihalides to form the complexes [Cd(DMP)Cl2]n and [M(DMP)2X2] (M = Cd, X = Br or I; M = Zn, X = Cl, Br or I). On the basis of their infrared spectra, the 1:2 adducts should have a distorted tetrahedral configuration, whereas the [Cd(DMP)Cl2]n complex probably has a polymeric structure formed by bridging chlorine atoms. The thermal behaviour of the DMP adducts is compared with that of the 2,6-dimethyl-4H-pyran-4-thione (DMTP) analogues of general formulae [M(DMTP)2X2] (M = Cd or Zn; X = halide) and [Cd(DMTP)Cl2]n.

Abstract
The carbonyl donor 2,6-dimethyl-4H-pyran-4-one (DMP) reacts with zinc and cadmium dihalides to form the complexes [Cd(DMP)Cl2]n and [M(DMP)2X2] (M = Cd, X = Br or I; M = Zn, X = Cl, Br or I). On the basis of their infrared spectra, the 1:2 adducts should have a distorted tetrahedral configuration, whereas the [Cd(DMP)Cl2]n complex probably has a polymeric structure formed by bridging chlorine atoms. The thermal behaviour of the DMP adducts is compared with that of the 2,6-dimethyl-4H-pyran-4-thione (DMTP) analogues of general formulae [M(DMTP)2X2] (M = Cd or Zn; X = halide) and [Cd(DMTP)Cl2]n.File in questo prodotto:
