The material structure described by Ba6Ge2N7 crystallizes in the trigonal R-3 space group. Ba(1) is bonded in a 6-coordinate geometry to one N(2) and five equivalent N(1) atoms. Ge(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to five equivalent Ba(1) and one Ge(1) atom. In the second N site, N(2) is bonded in an octahedral geometry to six equivalent Ba(1) atoms. is represented by the CIF file [CIF]
