摘要
Previously unknown [ML2(H2O) (n) ] bischelates, where M is Mn(II), Co(II), Ni(II), or Cu(II) and L is deprotonated triformylmethane, are studied by X-ray diffraction analysis. It is revealed that in the crystals of all compounds there are multiple hydrogen bonds linking bischelate molecules into polymer layers or a single framework. The character of the temperature dependence of the effective magnetic moment [ML2(H2O) (n) ] indicates the existences of weak intracrystalline exchange interactions between the unpaired electrons of the paramagnetic centers.
