Abstract
The bimetallic networks coordinated with oxalate bridges {〚M IIM III(C 2O 4) 3〛 –C +〛} n form an important family of molecular magnets. The role of the cation C + is fundamental for the nature of the obtained network (bi- or tridimensional). Thus, tridimensional polymers can be obtained in optically active forms using monocationic resolved templates such as 〚Ru(bpy) 2ppy〛 + 1 and 〚Ru(bpy) 2Quo〛 + 2. These cations were synthesized and resolved. A 1H NMR technique based on the formation of diastereomeric salts obtained with optically active anion 〚ΔTrisphat〛 – {Trisphat = tris(tetrachlorobenzenediolato)phosphate(V)} was used to measure the enantiomeric excesses.
