Trisodium bis-{1-[iminio-(morpholino)meth-yl]guanidinium} bis-[hexa-hydrogen-hexa-molybdoaluminate(III)] chloride icosa-hydrate.

ABSTRACT: In the title compound, Na(3)(C(6)H(15)N(5)O)(2)[Al(OH)(6)Mo(6)O(18)](2)Cl·20H(2)O, the [Al(OH)(6)Mo(6)O(18)](3-) polyoxo-anion has a B-type Anderson structure exhibiting approximate D(3d) symmetry. There are two types of sodium cations: the Na(+) cations of type I have a distorted octa-hedral coordination geometry formed by six O atoms and are statistically distributed over two positions with equal occupancies, while the coordination polyhedra of the two Na(+) cations of type II share one Cl anion located on an inversion center. The latter fragment, containing a Cl anion and two sodium cations, links two polyoxoanions into centrosymmetric blocks. The diprotonated 1-[imino-(morpholino)meth-yl]guanidinium cations and uncordinated water mol-ecules contribute to extensive N-H⋯O and O-H⋯O hydrogen bonding, resulting in the formation a three-dimensional supra-molecular structure.
