The complex of [4Ni (salen)·GGH] CLO₄·EtOH·H₂O has been synthesized and studied by X-ray single crystal analysis. The results show that there are both intra-unit hydrogen bonds in the [4Ni (salen)·GGH]⁺ and inter-unit hydrogen bonds between the two [4Ni (salen)·GGH]⁺. Ni (salen) in the unit are still centrosymmetric dimers with planar structure. Imide N(10)-H(10) in the [GGH]⁺ bonds with one phenolic oxygen 0(7) of Ni (salen) dimer in the same unit. Two H atoms of amino group N (9)-H[H (A), H (C)] in the glycylglycine perchlorate interact with phenolic oxygen[0 (3), 0 (5)] of [4Ni (salen)·GGH]+ through two strong hydrogen bonds respectively.
