The title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(20)H(21)NO(4))(2)], forms dimers of the paddle-wheel cage type located at crystallographic inversion centres. The two Zn atoms [Zn.Zn = 3.0533 (4) A] are connected by four syn-syn benzoate ligands. The apical positions of the square-pyramidal zinc coordination polyhedra are occupied by the N atoms of the papaverine ligand. Upon coordination, the mutual orientation of the phenyl and isoquinoline rings in papaverine is changed compared with that in the uncoordinated ligand.
标题配合物[Zn₂(C₇H₅O₂)₄(C₂₀H₂₁NO₄)₂]形成位于晶体学反演中心的桨轮笼型二聚体。两个锌原子[Zn-Zn = 3.0533(4) Å]通过四个顺-顺苯甲酸酯配体相连。四方锥型锌配位多面体的顶端位置由罂粟碱配体的N原子占据。配位后,罂粟碱中苯基和异喹啉环的相互取向与未配位配体中的相比发生了变化。
