The dehydrated copper silicate Na(2)[Cu(2)Si(4)O(11)]: a three-dimensional microporous framework with a linear Si—O—Si linkage
The structure of the title dehydrated copper silicate, disodium dicopper undecaoxide tetrasilicate, Na(2)(Cu(2)O(11)Si(4)), was determined by single-crystal X-ray diffraction from a non-merohedral twin. It exhibits an effective three-dimensional microporous framework with the major channels, in wh...

description | The structure of the title dehydrated copper silicate, disodium dicopper undecaoxide tetrasilicate, Na(2)(Cu(2)O(11)Si(4)), was determined by single-crystal X-ray diffraction from a non-merohedral twin. It exhibits an effective three-dimensional microporous framework with the major channels, in which the Na(+) cations are placed, running along the a-axis direction and smaller channels observed along the b-axis direction. The structure is unusual in that it contains a symmetry-constrained Si—O—Si angle of 180°. The Cu centre is coordinated to five O atoms, exhibiting a slightly distorted square-pyramidal coordination geometry. The Na cation is interacting with five neighbouring O atoms, exhibiting an uncharacteristic coordination environment. |
