摘要

在结构化学领域，含有[OM4]四面体（M =金属阳离子）结构的晶体已经有很好的文献记载。然而，同时含有[OPb4]四面体和π共轭基团的化合物由于其结构复杂，报道较少。本文采用高温熔融法制备了一种新型硼酸铅——Pb9O4(BO3)2(NO3)4。值得注意的是，Pb9O4(BO3)2(NO3)4的结构中含有由[OPb4]四面体形成的特殊[O8Pb18]∞链。该化合物具有较大的光学各向异性，在546 nm处双折射率为Δn = 0.117。

Pb9O4(BO3)2(NO3)4: A Lead Borate–Nitrate Containing an Anion-Centered [O8Pb18]∞ Chain with Large Optical Anisotropy

In the field of structural chemistry, crystals containing the [OM₄] tetrahedra (M = metal cation) structure have been well documented. However, compounds containing both [OPb₄] tetrahedra and π-conjugated groups are less reported due to their structural complexity. In this work, a new lead borate–nitrate, Pb₉O₄(BO₃)₂(NO₃)₄, has been synthesized by a high temperature melt method. Notably, the structure of Pb₉O₄(BO₃)₂(NO₃)₄ contains special [O₈Pb₁₈]_∞ chains formed by the [OPb₄] tetrahedra. This compound possesses a large optical anisotropy with birefringence of Δn = 0.117 at 546 nm.
