Bis(tetra-n-butylammonium) bis(μ-1,2-dicyanoethene-1,2-dithiolato-κ³S,S′:S′)bis[(1,2-dicyanoethene-1,2-dithiolato-κ²S,S′)cobalt(III)]

Abstract

In the title compound, (C(16)H(36)N)(2)[Co(C(4)N(2)S(2))(2)](2), pairs of [Co(C(4)N(2)S(2))(2)](-) anions combine to form discrete crystallographically centrosymmetric dimers, which stack along the c axis, surrounded by the counter-cations. The metal atom in the anion has a five-coordinate distorted square-pyramidal geometry.

Structure and properties of two polymorphs of tetra-n-butylammonium bis(maleonitriledithiolato)platinate(1−)

“…In previous work, we performed structural characterization of (NBu4)[Ni(mnt)2] and (NBu4)2[Co(mnt)2]2 [8,9]. Because the nickel complex exhibits a first-order paramagneticdiamagnetic phase transition at around 170 K [10], we were interested in the results when different metal atoms were used.…”
