Poly[bis(methanol-κO)tris(μ-pyrimidine-κ2N:N′)tetrakis(thiocyanato-κN)dinickel(II)]

Abstract

In the crystal structure of the title compound, [Ni2(NCS)4(C4H4N2)3(CH3OH)2]n, each nickel(II) cation is coordinated by three N-bonded pyrimidine ligands, two N-bonded thiocyanate anions and one O-bonded methanol molecule in a distorted octahedral environment. The asymmetric unit consists of one nickel cation, two thiocyanate anions and one methanol molecule in general positions, as well as one pyrimidine ligand located around a twofold rotation axis. The crystal structure consists of μ-N:N′ pyrimidine-bridged zigzag-like nickel thiocyanate chains; these are further linked by μ-N:N-bridging pyrimidine ligands into layers which are stacked perpendicular to the b axis. The layers are connected via weak O—H...S hydrogen bonding.
