Popis:	The title compounds, conveniently abbreviated Eu(DMH)3·o-phen and Eu(DMH)3·dipy, have been prepared and characterized by means of their luminescence spectra and by complete structure determination by X-ray diffraction. The spectral results indicated the existence of two europium sites in the dipy compound but only one in the o-phen complex. The X-ray results show that the o-phen complex has a single geometry, the coordination polyhedron of which is best approximated as a square antiprism, whereas there are two geometries in the dipy complex, both of which are also square antiprisms but are more distorted. In all cases the chelate rings span the s edges of the square antiprism and the bond distances are typical for this type of complex.
