Materials Data on PbS by Materials Project

PbS crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one PbS sheet oriented in the (0, 0, 1) direction. Pb2+ is bonded to five equivalent S2- atoms to form a mixture of distorted edge and corner-sharing PbS5 square pyramids. There are a spread of Pb–S bond distances ranging from 2.69–3.02 Å. S2- is bonded in a single-bond geometry to five equivalent Pb2+ atoms.

硫化铅（PbS）以单斜晶系C2/m空间群结晶。其晶体结构为二维型，包含一个沿(0, 0, 1)方向取向的PbS片层。Pb²+与五个等价的S²-成键，形成兼具畸变棱共享与角顶共享特征的PbS5四方锥配位多面体。Pb-S键长分布区间为2.69~3.02 埃（Å）。S²-以单键配位几何模式，与五个等价的Pb²+形成配位键。
