Ph2P(O)CH2CH2P(O)Ph2] ion-pair complex with mixed valence states was synthesized. Its structure was determine by x-ray diffraction. Triclinic, space group P1 , a 11.761(3), b 12.860(2), c 21.428(3) ? a 81.45(2), b 82.47(2), g 79.84(2)? Z = 1, R = 0.065, Rw = 0.075. CoI and CoII possess different polyhedral configurations, resp. The stability of the complex is explained by MO calculation
