首次合成了具有磁性的（C25 H23 N3 O3 Cl）CrMn（C2 O 4）3·H2O分子，其螺吡喃阳离子在侧链上含有季铵化的吡啶片段.该化合物具有铁磁性（Tc = 5.2K）和光致变色性质。通过电子光谱和红外光谱研究了杂化物的光化学性质。螺吡喃阳离子的光致变色转变伴随着电子光谱中400-600 nm区域的宽吸收带的出现和942 cm−1处的ν（Cspiro-O）IR带强度的降低。
A molecular magnetic (C25H23N3O3Cl)CrMn(C2O4)3·H2O whose spiropyran cation contains a quaternized pyridine fragment in the side aliphatic chain was synthesized for the first time. The compound possesses the properties of a ferromagnetic withTc= 5.2 K and photochromic properties in the crystalline state. The photochemical properties of the hybrid compound were studied by electronic and IR spectroscopies. Photochromic transformations of the spiropyran cation are accompanied by the appearance of a broad absorption band in the region 400–600 nm in the electronic spectra and by reduction of intensity of the ν(Cspiro-O) IR band at 942 cm−1.
