摘要:
X射线晶体学很少能捕捉到所讨论结构中原子之间的化学键合。大多数情况下,会应用基于距离的启发式方法来确定键合原子对。其中一类此类启发式方法依赖于一组键径参数,用于估算每种化学元素在键中的理想尺寸。本文提出了一种无监督方法,通过晶体结构数据推导键径参数,改进传统基于距离的启发式方法。
英文摘要:
X-ray crystallography rarely captures chemical bonding between atoms of a structure in question. Most of the time distance-based heuristics are applied to establish the pairs of bonded atoms. One class of such heuristics depends on a set of bonding radii that estimate the idealised size of each chemical element in a bond. This publication describes an unsupervised workflow for deriving a bonding radii set from crystal structure data in the Crystallography Open Database.
