Nickel(II) di-aqua complex containing a water cluster: synthesis, X-ray structure and catecholase activity
A trans-diaquanickel(ii) complex of the type [(L2-)Ni-II(H2O)(2)]center dot nH(2)O (1 center dot nH(2)O) was isolated, where LH2 is (E)-2-(2-((2-hydroxyphenylimino)methyl)phenoxy)acetic acid (LH2), a tetradentate ligand. The molecular geometry of 1 center dot nH(2)O was confirmed by single crystal X-ray structure determination. It is observed that in the crystal, coordinated water, bulk water and ligand oxygen atoms form six membered water clusters by OHMIDLINE HORIZONTAL ELLIPSISH interactions. 1 center dot nH(2)O has emerged as a catalyst for the oxidation of 3,5-di-tert-butylcatecholto 3,5-di-tert-butyl-o-benzoquinone with a turnover number (k(cat)) of 4.46 x 10(2) h(-1) in CH3OH. During oxidation, the coordination of catechol to the nickel(ii) centre and the formation of an o-benzosemiquinone intermediate were confirmed by a nickel based EPR signal, ESI mass spectrometry and UV-vis spectra. 1 center dot nH(2)O exhibits an irreversible anodic peak at 0.83 V versus the Fc(+)/Fc couple due to the phenoxyl/phenolato redox couple, authenticated by DFT calculations.
