Abstract. The self‐assembly of glycyl‐ L ‐leucine, Cu(NO 3 ) 2 · 3H 2 O and 4, 4′‐bipyridine resulted in the tetranuclear‐based metal‐dipeptide supramolecular framework [Cu 4 (C 8 H 14 N 2 O 3 ) 4 (H 2 O) 2 (C 10 H 8 N 2 ) 2 ] · (C 10 H 8 N 2 ) · 13H 2 O ( 1 ). In the structure, the 4, 4′‐bipyridine‐bridged tetranuclear complex of Cu II ‐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 [Cu 2 (C 8 H 14 N 2 O 3 ) 2 (C 10 H 8 N 2 )] · 2H 2 O ( 2 ), which is linked into a 2D hydrogen‐bonded structure without 4, 4′‐bipyridine included.
