• In this paper, we discuss the origin of magnetic chirality of chiral magnets made by chromium (III) and manganese (II) ions. Structurally characterized yellow needles : K_<0.4>[Cr(CN)_6][Mn(S)-pn](S)-pnH_<0.6> ((S)-pn=(S)-1, 2-diaminopropane) and green needles : [Cr(CN)_6][Mn(S or R)-pnH(H_2O)]H_2O were obtained by the reaction among K_3[C_r(CN)_6], Mn(ClO_4)_2, (R or S)-pn・2HCl and KOH. The space groups of green needle and yellow needle are P2_12_12_1 and P6_1, respectively. From the X-ray crystallographic analysis of them, the yellow needle has three-dimensional and green needle has two-dimensional magnetic connectivity. These ferrimagnets are good candidates for chiral spin order at low temperature. We present some theoretical supports, within classical phenomenologies, to understand characteristic features of the chiral magnetic materials and their magnetic properties.
