A Hexanuclear Niobium Cluster Compound Crystallizing as Macroscopic Tubes.

ABSTRACT: Compounds with ordered structures in one or two dimensions are exciting materials and investigated intensively in many different areas of science. Many activities have been put into the preparation of low-dimensional nano-scaled structures and many compounds in this size regime are known. Contrary, the number of known compounds that have low-dimensional macroscopic sized structures that form directly in a chemical reaction is very limited. Here, we present the synthesis of the niobium cluster compound [(Et₂ O)₂ H]₂ [Nb₆ Cl₁₈ ], crystals of which grow in form of large hexagonal empty tubes of several centimeter length and diameters in the range of 2 mm. The single-crystal X-ray structure of this compound has been refined. Under warming,
