ZnC2N3H2F crystallizes in the trigonal R-3c space group. Zn(1) is bonded to one N(2), two equivalent N(1), and two equivalent F(1) atoms to form corner-sharing ZnN3F2 trigonal bipyramids. The Zn(1)-N(2) bond length is 2.01 Å. Both Zn(1)-N(1) bond lengths are 2.03 Å. Both Zn(1)-F(1) bond lengths are 2.06 Å. C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.31 Å. The C(1)-N(2) bond length is 1.35 Å. The C(1)-H(1) bond length is 0.93 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one Zn(1) and two equivalent C(1) atoms. In the second N site, N(1) is bonded in a 3-coordinate geometry to one Zn(1), one C(1), and one N(1) atom. The N(1)-N(1) bond length is 1.37 Å. H(1) is bonded in a single-bond geometry to one C(1) atom. F(1) is bonded in a bent 120 degrees geometry to two equivalent Zn(1) atoms. Linkers: 7 C1=NN=C[N]1 ,9 [N]1=CN=NC=1 ,2 C1=NC=N[N]1.
