Abstract:
catena-Poly[aluminium(III)-μ-hydroxido-κ2 O:O-di-μ-methane-sulfonato-κ4 O:O'], [Al(OH)(CH3SO3)2] n , was prepared by mild hydro-thermal synthesis at 523 K and crystallizes as millimetre-sized clear and colourless needles. The asymmetric unit contains half of the repeating structure, one-dimensional (AlO6)∞ chains corner sharing through the axial hydroxyl group with a bend of ∼137ο. The extended structure shows the chains are connected through weak meth-yl-hydrogen bonding in the [001] direction and strong hydrox-yl-hydrogen bonding in the [100] direction. This is the second aluminium-based methane-sulfonate salt reported to date.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
