Crystal structure of hexa-kis-(dmpu)-di-?2-hydroxido-dialuminium tetraiodide dmpu tetra-solvate [dmpu is 1,3-di-methyl-tetra-hydro-pyrimidin-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-di-methyl-tetra-hydro-pyrimidin-2(1H)-one-?O]aluminium} tetra-iodide 1,3-di-methyl-tetra-hydro-pyrimidin-2(1H)-one tetra-solvate), 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 non-coordinating iodide anions compensate the charge of the complex cation. The remaining solvent mol-ecules and the iodide counter-anions inter-act with the complex cation by weak non-classical C-H?I and C-H?O hydrogen bonds.
