NaSrReCd crystallizes in the trigonal R3m space group. Na(1) is bonded to three equivalent Re(1) and one Cd(1) atom to form distorted NaCdRe3 trigonal pyramids that share  a cornercorner with one Re(1)Na3SrCd trigonal bipyramid, corners with three equivalent Cd(1)NaSr3Re trigonal bipyramids, and corners with six equivalent Na(1)CdRe3 trigonal pyramids. All Na(1)-Re(1) bond lengths are 2.99 Å. The Na(1)-Cd(1) bond length is 2.17 Å. Sr(1) is bonded in a distorted single-bond geometry to one Re(1) and three equivalent Cd(1) atoms. The Sr(1)-Re(1) bond length is 2.17 Å. All Sr(1)-Cd(1) bond lengths are 2.99 Å. Re(1) is bonded to three equivalent Na(1), one Sr(1), and one Cd(1) atom to form distorted ReNa3SrCd trigonal bipyramids that share corners with six equivalent Re(1)Na3SrCd trigonal bipyramids,  a cornercorner with one Na(1)CdRe3 trigonal pyramid, and edges with three equivalent Cd(1)NaSr3Re trigonal bipyramids. The Re(1)-Cd(1) bond length is 2.17 Å. Cd(1) is bonded to one Na(1), three equivalent Sr(1), and one Re(1) atom to form distorted CdNaSr3Re trigonal bipyramids that share corners with six equivalent Cd(1)NaSr3Re trigonal bipyramids, corners with three equivalent Na(1)CdRe3 trigonal pyramids, and edges with three equivalent Re(1)Na3SrCd trigonal bipyramids.
