| Abstract: | Abstract. The self‐assembly of glycyl‐L ‐leucine, Cu(NO3)2 · 3H2O and 4, 4′‐bipyridine resulted in the tetranuclear‐based metal‐dipeptide supramolecular framework Cu4(C8H14N2O3)4(H2O)2(C10H8N2)2] · (C10H8N2) · 13H2O ( 1 ). In the structure, the 4, 4′‐bipyridine‐bridged tetranuclear complex of CuII‐glycyl‐L ‐leucine interacts with each other to form a 1D hydrogen‐bonded chain including uncoordinated 4, 4′‐bipyridine and an interesting water chain in different channels. Under similar reaction conditions, racemic glycyl‐D ,L ‐leucine gave rise to the centrosymmetric dinuclear complex Cu2(C8H14N2O3)2(C10H8N2)] · 2H2O ( 2 ), which is linked into a 2D hydrogen‐bonded structure without 4, 4′‐bipyridine included. |
