摘 要：The search for new coordination assemblies exhibiting long-range magnetic ordering has attracted much attention over the past few decades.[1]Among them,cyanide-based transition metal materials has been one of the major research *** assemblies derived from[M（CN）6]3-（M=Cr,Fe,Co）and[M（CN）8]3/4-（M=Mo,W）building blocks and various transition metal or rare earth metal ions have been extensively explored.[2,3]In contrast to the highly symmetrical hexa-and octacyanometallate building blocks,the geometry of the heptacyanometallates block can lead to the formation of low-symmetry extended networks,which is an important feature for designing high-temperature molecular magnets with interesting anisotropic magnetic properties.[4]While,because of handling difficulties,low-symmetry extended heptacyanometalate-based magnets are less commonly *** introduction dimethylamine cation,we synthesized a 3D magnet based on[MoⅢ（CN）7]4-.Magnetic investigations revealed that the compound ordered ferrimagnetically with a small hysteresis effect.
