Through the study of the Cs–O bonds registered in the literature one observes that: (i) the bond lengths range from 2.46 to 3.60 A; (ii) the preferential coordination numbers adopted by the caesium ions are 8, 9 and 10 but values from 1 to 12 also

Two new mixed valent Mo(III)/Mo(IV) diphosphates containing lead Pb2(PbO)2Mo8(P2O7)8 and PbK2Mo8(P2O7)8 have been synthesized. The [Mo8P16O56]∞ frameworks of these phosphates are closely related to that of K0.17MoP2O7: the MoO6 octahedra and P2O7 g

The single crystal structure of a series of nine isotypic Mo(V) diphosphates was determined from crystals with composition A {sup 2+}(MoO){sub 10}(P{sub 2}O{sub 7}){sub 8} (A=Ba, Sr, Ca, Cd, Pb) and A {sup +}(MoO){sub 5}(P{sub 2}O{sub 7}){sub 4} (A=A

A Mo(III) lead phosphate, Pb2Mo(P2O7)(PO4), has been synthesized for the first time. This original structure, is built up of PO4 tetrahedra, P2O7 groups and MoO6 octahedra, sharing corners. Each P2O7 group shares two apices with the same MoO6 octahed

A Mo(III) cadmium diphosphate, Cd 5 Mo 2 (P 2 O 7 ) 4 has been synthesized for the first time. Its structure determination shows that the crystal chemistry of this new monoclinic phosphate is complex, due to the ability of cadmium to behave either as
