The crystal structure described by Be2Co(NF7)2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Be2Co(NF7)2 clusters. Be(1) is bonded to one F(1), one F(5), one F(6), and one F(7) atom to form BeF4 tetrahedra that share  an edgeedge with one Co(1)F6 octahedra. Co(1) is bonded to two equivalent F(3), two equivalent F(5), and two equivalent F(6) atoms to form CoF6 octahedra that share edges with two equivalent Be(1)F4 tetrahedra. N(1) is bonded in a trigonal non-coplanar geometry to one F(2), one F(4), and one F(7) atom. There are seven inequivalent F sites. In the first F site, F(7) is bonded in a bent 120 degrees geometry to one Be(1) and one N(1) atom. In the second F site, F(1) is bonded in a single-bond geometry to one Be(1) atom. In the third F site, F(2) is bonded in a single-bond geometry to one N(1) atom. In the fourth F site, F(3) is bonded in a single-bond geometry to one Co(1) atom. In the fifth F site, F(4) is bonded in a single-bond geometry to one N(1) atom. In the sixth F site, F(5) is bonded in an L-shaped geometry to one Be(1) and one Co(1) atom. In the seventh F site, F(6) is bonded in an L-shaped geometry to one Be(1) and one Co(1) atom. is represented by the CIF card [CIF]
