Ti2Nb6Cl14O4: A Unique 2D–1D Network Combination in Niobium Cluster Chemistry

Layers of niobium clusters that are linked to each other through zigzag chains of edge-sharing TiCl₄O₂] ocatahedra are the central structural features of the title compound. Bridging of the chains by (Nb₆Cl₈ⁱO₄ⁱ)Cl₆^a]⁶⁻ clusters results in the formation of empty tunnels (a section of the structure is shown on the right).
