Abstract The use of the pyN 4 coordination cap to synthesize high‐nuclearity clusters supported by polycyanometallate units was explored. The heptanuclear bimetallic complexes 2 and 3 were obtained as their salts by reacting stoichiometric amounts of pyN 4 and Ni(ac) 2 with K 3 [Fe(CN) 6 ] and K 4 [Mo(CN) 8 ], respectively. The tetranuclear complex 4 formed as a by‐product in the synthesis of 3 . Temperature‐dependent magnetic susceptibility measurements carried out for 2 revealed that this compound behaves as a paramagnet over the whole range of temperatures.
