Abstract:
In the title salt, (C10H9N2)(2) [Zn(C4N2S2)(2)].C2H3N or [4,4'-
bipyH][Zn(mnt)(2)].C2H3N, where mnt(2-) denotes
maleonitriledithiolate and 4,4'-bipyH is monoprotonated 4,4'-
bipyridine, the Zn-II ion is tetrahedrally surrounded by four S
atoms of two mnt(2-) ligands. The counter-cations, 4,4'-
bipyH(+), form one-dimensional chains through strong
(pyridine)N- H...N(pyridine) hydrogen-bonding interactions.
Anions and cations stack in alternating layers which are nearly
parallel to the bc plane of the crystallographic unit cell.
