The hydrothermal reaction of Cu(NO 3 ) 2 · 3 H 2 O, K 3 Fe(CN) 6 , and 1,10‐phenanthroline (1,10‐phen) or 2,2'‐bipyridine (2,2'‐bpy) gives rise to the three one‐dimensional helical‐chain complexes [Cu 2 Fe(CN) 4 (1,10‐phen) 3 ] n · 0.5 n H 2 O ( 1 ), [Cu 3 (CN) 3 (1,10‐phen) 3 ] n ( 2 ), and [Cu 3 (CN) 3 (2,2'‐bpy) 3 ] n ( 3 ), and the two‐dimensional layer complex [Cu 3 Fe(CN) 5 (2,2'‐bpy) 2 ] n ( 4 ). The structure of 1 contains a cyanide‐bridged Cu I ··· Fe II ··· Cu I chain in which the two copper and one iron centers exhibit different coordination environments. The structures of 2 and 3 are both monometallic. Complex 4 is constructed alternately from fused 6‐ and 14‐metal‐membered nonplanar centrosymmetric rings that form a 2D layer architecture.
