Several Mn II compounds have been synthesised with the phenylcyanamido ligand, C 6 H 5 −NCN − , and characterised by means of single crystal X‐ray structure determination. The reported compounds show a wide variety of nuclearity: mononuclear, dinuclear, 1‐D, and 2‐D compounds are present in which the phenylcyanamido anion (pcyd − ) acts as a bridging ligand. The mononuclear compound [Mn(pcyd) 2 (phen) 2 ] ( 1 ) crystallises in the orthorhombic system, Pbcn space group; dinuclear compound [{Mn(pcyd)(phen)(MeOH)} 2 (μ 1,3 ‐pcyd) 2 ] ( 2 ) crystallises in the monoclinic system, C 2/ c space group; 1‐D chain [Mn(4‐bzpy) 2 (μ 1,3 ‐pcyd) 2 ] n ·MeOH ( 3 ·MeOH) crystallises in the triclinic system, P $\bar 1$ space group; 2‐D network [Mn(μ 1,3 ‐pcyd) 2 (μ‐4,4′‐bpy)] n ·MeOH ( 4 ·MeOH) crystallises in the monoclinic system, C2 space group. Susceptibility measurements on compounds 2 − 4 reveal moderate AF coupling in all cases. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
