The crystal structure described by BaReH7 crystallizes in the monoclinic P2_1/m space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent H(2) and four equivalent H(4) atoms. Re(1) is bonded in a 7-coordinate geometry to one H(1), two equivalent H(2), two equivalent H(3), and two equivalent H(4) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Re(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one Re(1) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to one Re(1) atom. In the fourth H site, H(4) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one Re(1) atom. is represented by the CIF file [CIF]
