The reaction between s-cis-diaqua-(ethylenediamine-N,N′-diacetato)-chromium(III) nitrate and glycine (mole ratio 1:1, pH = 6, 80 °C, 2 h) results in the formation of two nonelectrolytic compounds. One of them was identified as the title complex. The infrared and electronic absorption spectra, as well as the magnetic momentum confirm a binuclear structure and the existence of hydroxo and O, O′-glycinato bridges.
