摘 要:The complex of [4Ni(salen)·GGH] CLO_4·EtOH·H_2O 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.
