In the case of 1, three [LH]-7 units are coordinated to the 6-fold positively charged peroxo-Zr core, that is, two positive charges per [LH]7- are active. Thus the central Zrcore6+ acidifies the peripheral protons on [LH]7- in an unprecedented way¡£ Polyanion 1 represents thefirst structurally characterized Zr-peroxo POM with side-on, bridging peroxo units. |
