Abstract
Reaction of the ruthenium complexes [RuCl2(EPh3)3] (E=P, As), [(η5-C5H5)RuCl(EPh3)2] (E=P, As), [(η5-C5Me5)RuCl(PPh3)2] and [(η5-C9H7)RuCl(PPh3)2] with 2,6-diacetylpyridinemonoxime (dapmoH) have been investigated. Compounds with the formulations [Ru(κ3-dapmoH)Cl(PPh3)2]PF6 (1), [Ru(κ3-dapmoH)Cl(PPh3)2]BF4 (2) and [Ru(κ3-dapmoH)Cl(AsPh3)2]Cl (3) have been isolated and fully characterized by elemental analyses, IR, NMR, electronic, emission spectral and electrochemical studies. Molecular structures of the complexes [Ru(κ3-dapmoH)Cl(PPh3)2]PF6•H2O (1) and RuK3-dapmoH)Cl(PPh3)2BF4•1•52O 2(2) have been determined by single crystal X-ray diffraction studies. A structural feature of interest for both the compounds is that the counter anions in 1 and 2 play vital role in the self-assembly of cages through intermolecular weak interactions in which water dimers or trimers are encapsulated. Compounds 1 and 2 strongly emit upon excitation at their respective MLCT transitions.
