Cp. Cui et al., A tetranuclear copper complex, [Cu-4(mu(3)-OH)(2)(mu(2)-OH)(2)(phen)(4)(H2O)(2)](NO3)(4)center dot 2H(2)O, ACT CRYST E, 57, 2001, pp. M198-M200
The crystal structure of the title compound, diaquadi-mu (3)-hydroxo-di-(mu
)2--hydroxo-tetraphenanthrolinetetracopper(II) tetranitrate dihydrate, [Cu-
4(OH)(4)(C10H8N2)(4)(H2O)(2)]-(NO3)(4). 2H(2)O, was determined by single-cr
ystal X-ray diffraction. The tetranuclear copper structure has a chair form
and each copper has a tetragonal pyramidal coordination geometry. The comp
ound was synthesized by the hydro(solvo)thermal method and there is a fluor
escence peak at 450 nm.
