(CuH6(C2N)3)2SiF6 is Indium-derived structured and crystallizes in the tetragonal I4/mcm space group. The structure is zero-dimensional and consists of eight CuH6(C2N)3 clusters and four SiF6 clusters. In each CuH6(C2N)3 cluster, Cu(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(2) atoms. The Cu(1)-N(1) bond length is 2.00 Å. Both Cu(1)-N(2) bond lengths are 1.93 Å. There are two inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2) atom. The C(2)-N(1) bond length is 1.35 Å. The C(2)-H(2) bond length is 1.09 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(2) and one H(1) atom. The C(1)-N(2) bond length is 1.36 Å. The C(1)-H(1) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(2) atoms. In the second N site, N(2) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In each SiF6 cluster, Si(1) is bonded in an octahedral geometry to two equivalent F(2) and four F(1,1) atoms. Both Si(1)-F(2) bond lengths are 1.71 Å. All Si(1)-F(1,1) bond lengths are 1.73 Å. There are three inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to one Si(1) atom. In the second F site, F(1) is bonded in a single-bond geometry to one Si(1) atom. In the third F site, F(1) is bonded in a single-bond geometry to one Si(1) atom. Linkers: 2 c1cnccn1.
