Abstract	Two two-dimensional cyanide- and phenoxo-bridged heterometallic M(II)-Mn(III) (M = Ni, Pd) coordination polymers {[Mn(saltmen)]4[Ni(CN)4]}(ClO4)2·CH3OH·H2O (1) and {[Mn(saltmen)]4[Pd(CN)4]}(ClO4)2· CH3CN·H2O (2) (saltmen2– = N,N'-(1,1,2,2-tetramethylethylene)bis(salicylideneaminato)dianion) have been obtained by using K2[M(CN)4] as building blocks and a salen-tpye Schiff-base manganese(III) compound as assembling segment. Single X-ray analysis reveals their isostrutural cyanide-bridged MMn4 pentanuclear cationic structure. The four Schiff base manganese units of the pentanuclear entity are self-complementary through the phenoxo oxygen atoms from the neighboring complex, therefore forming cyanide- and phenoxobridged 2D sheet-like structure. Investigation over magnetic susceptibilities reveals the overall ferromagnetic coupling between the adjacent Mn(III) ions bridged by the phenoxo oxygen atoms with J = 2.13 and 2.21 cm−1 for complexes 1 and 2, respectively.
