A series of zinc complexes of 2,7-bis(2-pyridyl)-1,8-naphthyridine (BPNP) has been synthesised and characterised by single crystal X-ray diffraction and solution state NMR spectroscopic studies. Reactions of BPNP with zinc acetate and zinc chloride were found to give mononuclear complexes of the form [Zn(BPNP)X₂] (X = OAc, Cl), whereas reactions with zinc triflate led to a mixture of products. Several of these were identified crystallographically as [Zn(BPNP-H)(H₂O)₄](OTf)₃ and [Zn(BPNP-H)(NCMe)(OTf)₂]OTf, in which protonation of one pyridyl group occurred, and the dimeric species [Zn₂(BPNP)₄(μ-H₂O)₂](OTf)₄. A trimetallic complex [Zn₃(μ₂-BPNP)(μ₂-OAc)₃(OAc)₂(μ₃-OH)] was also isolated from reactions involving zinc acetate, and demonstrates the ability of BPNP to coordinate two zinc atoms in the adjacent binding pockets.

已经合成了一系列 2,7-双 (2-吡啶基)-1,8-萘啶 (BPNP) 的锌配合物，并通过单晶 X 射线衍射和溶液态核磁共振光谱研究对其进行了表征。发现 BPNP 与醋酸锌和氯化锌的反应产生 [Zn(BPNP)X ₂ ] (X = OAc, Cl)形式的单核配合物，而与三氟甲磺酸锌的反应导致产物的混合物。其中一些在晶体学上被鉴定为 [Zn(BPNP-H)(H ₂ O) ₄ ](OTf) ₃和 [Zn(BPNP-H)(NCMe)(OTf) ₂ ]OTf，其中一个吡啶基的质子化发生，二聚体 [Zn ₂ (BPNP) ₄ (μ-H ₂ O) ₂ ](OTf)₄ . 三金属配合物 [Zn ₃ (μ ₂ -BPNP)(μ ₂ -OAc) ₃ (OAc) ₂ (μ ₃ -OH)] 也从涉及醋酸锌的反应中分离出来，并证明了 BPNP 配位两个锌原子的能力在相邻的结合口袋中。
