Synthesis and crystal structure of two Co(III) α-dioximates with the formula [Co(DH)2(PPh3)(H2O)]2[EF6]·nH2O

The [Co(DH)2(PPh3)(H2O)]2[TiF6]·2.5H2O (1) and Co(DH)2(PPh3)(H2O)]2[ZrF6]·3.75H2O (2) complexes have been obtained from the CoEF6·6H2O - 2DH2 - PPh3 system, where DH2 is the dimethylglyoxime, E is Ti or Zr, and PPh3 is triphenylphosphine. The structure and composition of these complexes have bee...
