Crystal structure of hexa­kis­(dmpu)-di-μ2-hydroxido-dialuminium tetraiodide dmpu tetra­solvate [dmpu is 1,3-di­methyl­tetra­hydro­pyrimidin-2(1H)-one]: a centrosymmetric dinuclear aluminium complex containing AlO5 polyhedra

Abstract

The structure of the title compound, [Al2(OH)2(C6H12N2O)6]I4.4C6H12N2O (systematic name: di-2-hydroxido-bis{tris[1,3-dimethyltetrahydropyrimidin- 2(1H)-one-O]aluminium} tetraiodide 1,3-dimethyltetrahydropyrimidin-2(1H)-one tetrasolvate), is composed of two Al(C6H12N2O)3 moieties linked into a centrosymmetric dinuclear unit by a pair of bridging hydroxide ions. The aluminium cations show a distorted trigonal bipyramidal AlO5 coordination environment formed only by monodentate ligands. The Al-O bond lengths are in the range 1.789(2)-1.859(2) Å (mean bond length = 1.818 Å ). The noncoordinating iodide anions compensate the charge of the complex cation. The remaining solvent molecules and the iodide counter-anions interact with the complex cation by weak non-classical C-H...I and C-H...O hydrogen bonds.
