Re Sn Sb
ReSnSb crystallizes in the trigonal R3m space group. Re(1) is bonded in a distorted single-bond geometry to one Sn(1) and three equivalent Sb(1) atoms. The Re(1)-Sn(1) bond length is 1.53 Å. All Re(1)-Sb(1) bond lengths are 2.70 Å. Sn(1) is bonded in a distorted single-bond geometry to one Re(1) and four equivalent Sb(1) atoms. There is one shorter (2.72 Å) and three longer (2.84 Å) Sn(1)-Sb(1) bond lengths. Sb(1) is bonded to three equivalent Re(1) and four equivalent Sn(1) atoms to form a mixture of distorted edge and corner-sharing SbRe3Sn4 hexagonal pyramids.
