Phenylcyanamido Ligand Building Molecular, 1‐D, and 2‐D Systems − Syntheses, Crystal Structures and Magnetic Properties

Abstract

AbstractSeveral MnII compounds have been synthesised with the phenylcyanamido ligand, C6H5−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(μ1,3‐pcyd)2] (2) crystallises in the monoclinic system, C2/c space group; 1‐D chain [Mn(4‐bzpy)2(μ1,3‐pcyd)2]n·MeOH (3·MeOH) crystallises in the triclinic system, P$\bar 1$ space group; 2‐D network [Mn(μ1,3‐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)
