T. Ama et al., TRINUCLEAR COBALT(III) COMPLEXES CONTAINING PARTIAL CUBANE CO3O4 CORE- SYNTHESIS AND STRUCTURE OF [CO-3(L)(3)(MU-OH)(3)(MU(3)-O)]CL (L=ETHYLENEDIAMINE-N-ACETATE), Chemistry Letters, (4), 1995, pp. 267-268
Three isomers of [Co-3(edma)(3)(mu-OH)(3)(mu(3)-O)](+) (edma: ethylene
diamine-N-acetate) containing a partial cubane Co3O4 core were prepare
d and the structure of one of the isomers was determined by the X-ray
diffraction method. These isomers are stable at least for 5 days in th
eir neutral aqueous solutions.
