The structure described by BaReH9 crystallizes in the trigonal R32 space group. Ba(1) is bonded in a 18-coordinate geometry to six equivalent H(1) and twelve equivalent H(2) atoms. Re(1) is bonded in a 9-coordinate geometry to three equivalent H(1) and six equivalent H(2) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one Re(1) atom. In the second H site, H(1) is bonded in a single-bond geometry to two equivalent Ba(1) and one Re(1) atom. is represented by the CIF card [CIF]
