E. Goreshnik, M. Leblanc and V. Maisonneuve

Abstract: The title compound, (C10H28N4)[AlF5(H2O)]2·2H2O, obtained solvothermally at 473  K and isostructural with the iron analogue, consists of isolated [AlF5(H2O)] octahedral anions and centrosymmetric tetraprotonated 1,4,8,11-tetraazacyclodecane (cyclamH44+) moieties connected by a network of N-H...X (X = O,F) hydrogen bonds. One water molecule participates in the aluminium coordination, whereas the second water molecule connects two neighbouring [AlF5(H2O)] octahedra via F1...H2WB-O2-H2WA...F3 bridges.
