The diffusion reaction of Mn 2+ ions, the bidentate ligand dabco, and [Mo(CN) 8 ] 3– units at different temperatures produced 2D layer [Mn II (dabco)Mo V (CN) 8 ] 2 · [Mn II (H 2 O) 6 ] · 2H 2 O ( 1 ) and 3D network [Mn II (dabco)] 2 [Mn II (CH 3 OH) 4 ][Mo V (CN) 8 ] 2 · 2H 2 O ( 2 ). Structural analysis revealed that there are two independent central Mn atoms (Mn1 and Mn2) in the structure for each compound, which exhibit trigonal bipyramid and octahedral arrangement, respectively. Notably, the coordination mode of the Mn2 unit between layers in both compounds was responsible for the resulting structural dimensionalities. The crystal growth process of final products was dominantly controlled by the kinetics. The isolation of both compounds provides an insight into the effect of crystallization temperatures on the formation and structural conversion of manganese octacyanometalates.
