Poly[hydronium [dysprosium(III)-[mu]3-(ethylenediaminetetraacetato-[kappa]8N,N',O,O',O'',O''':O'''':O''''')] monohydrate]

Abstract top

The DyIII atom in the title compound, (H3O)[Dy(C10H12N2O8)]·H2O, is N,N',O,O',O'',O'''-chelated by the edta tetraanion; it is also linked to the O atoms of two other tetraaanions in the polyanionic layer. The metal atom (site symmetry m) exists in a square-antiprismatic DyO6N2 geometry. The tetraanion is disordered over a mirror plane. The oxonium cation and water molecule are disordered, in a 2:1 ratio, and these occupy the space between adjacent layers. They probably interact with the layers by way of O-H...O hydrogen bonds, but the H atoms could not be located.

Comment top

The erbium(III) and holonium(III) derivatives of edta have recently been reported (You et al., 2007a, b). The dysprosium analog described here is isostructural.

For the isostructural erbium(III) and holonium(III) analogs, see: You et al. (2007a,b).

Experimental top

Dysprosium(III) oxide (0.162 g, 0.5 mmol), ethylenediaminetetraacetic acid (edta) (0.286 g, 0.8 mmol), perchloric acid (0.385 mmol) and oxalic acid (0.042 g, 0.175 mmol) were dissolved in a mixture of methanol (5 ml) and water (5 ml). This solution was sealed in a Teflon-lined, stainless-steel autoclave (20 ml capacity) and heated to 433 K for 4 days. It was cooled to room temperature at 5 K h−1 to obtain colorless blocks of (I).

Refinement top

The edta tetraanion is disordered about a mirror plane; only the O1, O2 and C1 atoms of the molecule have full occupany, the other atoms being given 0.5 occupancy. For the disordered atoms, the C–O distances were restrained to 1.25±0.01 Å, the C–N distances to 1.45±0.01 Å and the C–C distances to 1.50±0.01 Å. The vibration of the ordered and disordered C, N and O atoms were restrained to be nearly isotropic.

Along with the [(C10H12N2O8)Dy] monoanion, the formula unit should have one hydronium ion and one water molecule; their respective O atoms are disordered and the sum of their occupancies should be unity. As the occupancy refined to 0.67 (1):0.33 (1), the occupancies were then fixed at this ratio. The 'o' and 'w' labels are arbitrary and do not mean that the O3o is the hydronium and the O1w the water O atoms. Their H atoms could not be placed with any confidence.

The carbon-bound H atoms were placed at calculated positions (C–H 0.97 Å), and they were included in the refinement in the riding model approximation with U(H) set to 1.2Ueq(C).
