Graphical Abstract
Magnetism gets a new twist: The crystal structure and magnetic properties of a chiral 3D ferrimagnet with Tc of 35 K, [{CrIII(CN)6}{MnII(d- or L-NH2ala)}3]⋅3 H2O (NH2ala=aminoalanine ion) are described. The complex has an extended, chiral, triple-strand helical arrangement of MnII ions, formed by the coordination of the organic ligands (see picture; purple Mn, gray C, blue N, red O). The triple helixes are linked to each other by the {CrIII(CN)6} units.

C5H9Cr0.33MnN4O3, Mr=245.44, hexagonal, P63 (No. 173), a=b=13.6802(16), c=8.1530(14) Å, V=1321.4(3) Å3, T=100 K, Z=6, ρcalcd=1.851 g cm−3, μ(MoKα)=1.870 mm−1. Data were collected with a Bruker SMART-APEX three-circle diffractometer, equipped with a CCD area detector (graphite-monochromated MoKα radiation, λ=0.71073 Å, ω-scan mode (0.3 ° steps), semi-empirical absorption correction on Laue equivalents). The structures were solved by direct method and refined by full-matrix least squares against F2 of all data, using SHELXTL software. All-non-hydrogen atoms were refined anisotropically. Hydrogen atoms, except for the water hydrogen atoms, were placed in calculated positions but not refined. The refinement converges with R1=0.0440 for 1192 data (I>2σ(I)), wR2=0.1169 for 1194 unique data (1.72≥θ≥23.24 °), Flack parameter=0.05(6), max/min residual electron density 0.566/−0.608 e Å3.
