Abstract: | Two hybrid compounds based on {Mo5O16} ribbon-like chains, M(3-pt)2(Mo5O16)]·H2O (M = Co, Mn) (1 and 2) {3-pt = 5-(3-pyridyl)-tetrazole}, have been hydrothermally synthesized and characterized by single crystal X-ray diffraction. Three-dimensional Mo/O/MII/tetrazole frameworks of the title compounds are constructed from 1D infinite ribbon-like Mo5O16]2− chains covalently linked through M(3-ptz)]2+ fragments via OM and NMo coordinate bonds. It is noteworthy that the isostructural compounds contain an unprecedented 3D bimetallic oxide network with 16-membered wheel clusters in which two parallel interdigitated stacks of 3-pt ligands are trapped. Remarkably, the title complexes represent the first two examples of the solid materials containing {Mo5O16} ribbon-like chains. |
