AbstractA new complex [Pr3NH]+[Mn(dca)3]− · H2O (dicyanamide = dca−) was synthesized, in which the Mn2+cations are bridged by end-to-end dca anions to form three-dimensional [Mn(dca)3]nn−networks and tripropylammonium cations reside in the cavities of these networks. The complex has been characterized by single-crystal X-ray diffraction, infrared spectroscopy, elemental analysis, and magnetic measurements. Magnetic susceptibility data indicate ferromagnetic interactions among the MnIIions.
