Abstract

We report the magnetic structure and properties of a thiocyanate-based honeycomb magnet [Na(OH₂)₃]Mn(NCS)₃ which crystallises in the unusual low-symmetry trigonal space group P [3 with combining macron] . Magnetic measurements on powder samples show this material is an antiferromagnet (ordering temperature T_N,mag = 18.1(6) K) and can be described by nearest neighbour antiferromagnetic interactions J = −11.07(4) K. A method for growing neutron-diffraction sized single crystals (>10 mm³) is demonstrated. Low temperature neutron single crystal diffraction shows that the compound adopts the collinear antiferromagnetic structure with T_N,neut = 18.94(7) K, magnetic space group P [3 with combining macron] ′. Low temperature second-harmonic generation (SHG) measurements provide no evidence of breaking of the centre of symmetry.
