| Abstract: | The new high‐spin iron(II) complex, Fe(C12H10N6)2(H2O)2](C8H3N4S)2 or Fe(abpt)2(H2O)2](tcnsme)2 where abpt is 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and tcnsme is the 1,1,3,3‐tetracyano‐2‐methylthiopropenide anion], consists of discrete Fe(abpt)2(H2O)2]2+ dications, where the FeII ion is coordinated by two N,N′‐bidentate chelating abpt ligands in the equatorial plane and two water molecules in trans positions, generating a distorted octahedral FeN4O2] environment. The cationic unit is neutralized by two polynitrile tcnsme anions, in which the C—N, C—C and C—S bond lengths indicate extensive electronic delocalization. In the crystal structure, the dications and anions are linked through O—H...N and N—H...N hydrogen bonds involving the water H atoms and those of the NH2 groups and the N atoms of the CN groups, leading to the formation of a three‐dimensional network. |
