NaZn2(BH4)5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of two NaZn2(BH4)5 frameworks. Na1+ is bonded in a 7-coordinate geometry to seven H+0.50+ atoms. There are a spread of Na–H bond distances ranging from 2.29–2.54 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 5-coordinate geometry to five H+0.50+ atoms. There are a spread of Zn–H bond distances ranging from 1.79–1.93 Å. In the second Zn2+ site, Zn2+ is bonded in a 6-coordinate geometry to six H+0.50+ atoms. There are a spread of Zn–H bond distances ranging from 1.83–2.15 Å. There are five inequivalent B3- sites. In the first B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There are a spread of B–H bond distances ranging from 1.21–1.27 Å. In the second B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There are a spread of B–H bond distances ranging from 1.21–1.27 Å. In the third B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There are a spread of B–H bond distances ranging from 1.20–1.25 Å. In the fourth B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There are a spread of B–H bond distances ranging from 1.20–1.26 Å. In the fifth B3- site, B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms. There is two shorter (1.21 Å) and two longer (1.26 Å) B–H bond length. There are twenty inequivalent H+0.50+ sites. In the first H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the second H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Na1+ and one B3- atom. In the third H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the fourth H+0.50+ site, H+0.50+ is bonded in a water-like geometry to one Na1+ and one B3- atom. In the fifth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Na1+ and one B3- atom. In the sixth H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the seventh H+0.50+ site, H+0.50+ is bonded in a distorted L-shaped geometry to one Zn2+ and one B3- atom. In the eighth H+0.50+ site, H+0.50+ is bonded in a distorted L-shaped geometry to one Na1+ and one B3- atom. In the ninth H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the tenth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one Zn2+ and one B3- atom. In the eleventh H+0.50+ site, H+0.50+ is bonded in a water-like geometry to one Zn2+ and one B3- atom. In the twelfth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one B3- atom. In the thirteenth H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the fourteenth H+0.50+ site, H+0.50+ is bonded in a distorted water-like geometry to one Na1+ and one B3- atom. In the fifteenth H+0.50+ site, H+0.50+ is bonded in an L-shaped geometry to one Zn2+ and one B3- atom. In the sixteenth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one B3- atom. In the seventeenth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Na1+ and one B3- atom.
