Crystal structure of an organic-inorganic hybrid compound based on morpholinium cations and a β-type Anderson polyanion.

Lukianova TJ, Kinzhybalo V, Pietraszko A - Acta Crystallogr E Crystallogr Commun (2015)

Bottom Line: The polyoxidomolybdate (POM) anion is of the Anderson β-type with a central Fe(III) ion.Three of five crystallographically independent morpholinium cations are disordered over two sets of sites.An intricate network of inter-molecular N-H⋯O and O-H⋯O inter-actions between cations, POMs, sulfate anions and non-coordinating water mol-ecules creates a three-dimensional network structure.

ABSTRACT
A new organic-inorganic hybrid compound, penta-morpholinium hexa-hydrogen hexa-molybdoferrate(III) sulfate 3.5-hydrate, (C4H10NO)5[Fe(III)(OH)6Mo6O18](SO4)·3.5H2O, was obtained from an aqueous solution. The polyoxidomolybdate (POM) anion is of the Anderson β-type with a central Fe(III) ion. Three of five crystallographically independent morpholinium cations are disordered over two sets of sites. An intricate network of inter-molecular N-H⋯O and O-H⋯O inter-actions between cations, POMs, sulfate anions and non-coordinating water mol-ecules creates a three-dimensional network structure.

fig1: The mol­ecular components in the structure of compound (I). Displacement ellipsoids are drawn at the 45% probability level. Hydrogen bonds are denoted by cyan dashed lines. Minor parts of the disordered cations are shown with dashed bonds.

Mentions: The asymmetric unit of compound (I) is made up of one Anderson β-type polyoxidoanion, [Fe(OH)6Mo6O18]3−, abbreviated in the following as {FeMo6}, five morpholinium cations (C4H10NO)+, one sulfate anion and four non-coordinating water mol­ecules (Fig. 1 ▸). Three of the morpholinium cations are disordered over two sets of sites and one water mol­ecule (O1W) shows half-occupancy. The {FeMo6} anion is formed by six edge-sharing [MoO6] octa­hedra, which are arranged hexa­gonally around the central [Fe(OH)6] octa­hedron with bond lengths and angles that are within the expected ranges for this type of POM anion (Cao et al., 2007 ▸). The six hydroxyl groups of the Anderson-type polyoxoanion are involved as donor groups in hydrogen-bond formation with O atoms of the sulfate anions and the non-coordinating water mol­ecules.
