Materials Data on RbNa2Al3Ge3O13 by Materials Project
Abstract
Rb2O2(Na2Al3(GeO4)3)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional and consists of two Rb2O2 ribbons oriented in the (1, 0, 0) direction and one Na2Al3(GeO4)3 framework. In each Rb2O2 ribbon, Rb is bonded in a 2-coordinate geometry to two equivalent O atoms. There are one shorter (2.87 Å) and one longer (2.89 Å) Rb–O bond lengths. O is bonded in a bent 150 degrees geometry to two equivalent Rb atoms. In the Na2Al3(GeO4)3 framework, there are two inequivalent Na sites. In the first Na site, Na is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Na–O bond distances ranging from 2.37–2.57 Å. In the second Na site, Na is bonded in a 5-coordinate geometry to seven O atoms. There are a spread of Na–O bond distances ranging from 2.38–2.92 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with four GeO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.74–1.78 Å. In the second Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners withmore »
