Three members of the homologous series of manganese oxyselenides with the general formula La2n+2MnSen+2O2n+2 (n = 0–2) have been synthesized in a NaI/KI flux and characterized by single-crystalX-raydiffraction,powderX-raydiffractionandmagneticmeasurements. Thestructures consist of chains of edge-sharing MnSe4O2-octahedra along the b-axis which are linked together along the a-axis by edge-sharing OLa4- and/or OLa3Mn-tetrahedra forming infinite ribbons of increasing width. mC-La2MnSe2O2 (Pb2HgCl2O2-type, C2/m, a = 11.6621(5) Å, b = 3.9719(1) Å, c = 7.2049(3) Å, β = 121.655(2)◦) represents a new polymorph of this compound. La4MnSe3O4 (P2/m, a = 9.0055(4) Å, b = 4.0186(1) Å, c = 7.1946(3) Å, β = 109.715(2)◦) and La6MnSe4O6 (C2/m, a = 24.760(2) Å,b = 4.0359(3)Å,c=7.1850(6)Å, β =104.162(3)◦)exhibitnewstructuretypes. Magnetic measurements suggest antiferromagnetic order of the moments below about 15 K with effective magnetic moments of 5.53(1), 5.99(1) and 6.01(1) µB per formula unit for n = 1, 2 and 3, respectively.
