CoC6H8(NCl)2C7H6 is Indium-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two 2,4-dimethyl-1,4-pentadiene molecules and two CoC6H8(NCl)2 clusters. In each CoC6H8(NCl)2 cluster, Co(1) is bonded in a tetrahedral geometry to one N(1), one N(2), and two equivalent Cl(1) atoms. The Co(1)-N(1) bond length is 2.04 Å. The Co(1)-N(2) bond length is 2.04 Å. Both Co(1)-Cl(1) bond lengths are 2.24 Å. There are four inequivalent C sites. In the first C site, C(3) is bonded in a distorted trigonal planar geometry to two equivalent C(5) and one N(1) atom. Both C(3)-C(5) bond lengths are 1.40 Å. The C(3)-N(1) bond length is 1.43 Å. In the second C site, C(4) is bonded in a distorted trigonal planar geometry to two equivalent C(6) and one N(2) atom. Both C(4)-C(6) bond lengths are 1.40 Å. The C(4)-N(2) bond length is 1.43 Å. In the third C site, C(5) is bonded in a distorted single-bond geometry to one C(3) and one H(3) atom. The C(5)-H(3) bond length is 1.09 Å. In the fourth C site, C(6) is bonded in a distorted single-bond geometry to one C(4) and one H(4) atom. The C(6)-H(4) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Co(1), one C(3), and two equivalent H(1) atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N(1)-H(1) bond lengths are 1.03 Å. In the second N site, N(2) is bonded to one Co(1), one C(4), and two equivalent H(2) atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N(2)-H(2) bond lengths are 1.03 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(6) atom. Cl(1) is bonded in a single-bond geometry to one Co(1) atom. Linkers: 1 Nc1ccc(Cc2ccc(N)cc2)cc1 ,1 [N]c1ccc(Cc2ccc(N)cc2)cc1. Metal clusters: 1 [Co].
