- Аннотация: A non-centrosymmetric orthorhombic diphosphate, Cs2Cu1+x(VO)2-x(P2O7)2 (x = 0.1) with a = 13.7364(2) Å, b = 9.2666(2) Å, c = 11.5678(2) Å, Z = 4, has been isolated. Its 3D framework is built from Cu atoms in square pyramidal and square planar coordination, VO5 tetragonal pyramids and P2O7 diphosphate groups, sharing vertices. Large channels are fulfilled by cesium atoms. The ESR study reveals a similarity in behaviour of two paramagnetic (Cu and V) subsystems. The temperature dependences of the ESR linewidth and static magnetic susceptibility data present evidences for a cluster type magnetic ordering in the title compound at T* = 22 K. The weakness of the relevant anomalies reflects presumably obvious Cu2+ ions and (VO)2+ units disorder in the system. It is supposed that the charge and geometry of the framework are controlled by the Cu2+/(VO)2+ ratio; its variation may lead to a design of new materials
