Na2Sn(NH2)6 crystallizes in the trigonal R-3 space group. Na(1) is bonded in a 9-coordinate geometry to nine equivalent N(1) atoms. Sn(1) is bonded in a cuboctahedral geometry to six equivalent N(1) and six equivalent H(2) atoms. N(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), one Sn(1), two equivalent N(1), and one H(1) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent H(1) atoms. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Sn(1) and one H(2) atom.
