铼的配位化学研究Ⅰ.铼化合物的堆积饱和规律

摘要: 将锝化合物稳定性研究中引入的改进的堆积模型用于锌化合物的稳定性研究。在查得４０６种不含金属－金属键的化合物结构基础上，对其立体角系数和（ＳＡＳ）进行了计算和分析，发现铼化合物的稳定中心（平均立体角系数和ＳＡＳ）为０．９５１，标准偏差（σ）为０．０８４，其２σ不大于一个常见配位原子的立体角系数（ＳＡＦ），这反映了铼周围配位原子堆积的限度。

Abstract: STUDY OF COORDINATION CHEMISTRY OF RHENIUM Ⅰ．PACKING　SATURATION RULELIU GOUZHENG；LIU BOLI（Department of Chemistry，Beijing Normal University，Beijing 100875）ABSTRACT The stahility of rhenium compounds in crystal is studied based on the reformed packingmodel．The structral data of 406 rhenium compounds containing no metal-metal bonds are col-lected．The sums of their solid angle factor（SAF）are calculated and statistically analysed．It turnsout that the stability center（SAS）is 0．951±0．084．The value of 2σ is comparable to the SAF ofa common coordinating atom.This result means that the packing of the coordinating atoms ar-round the central atom is restricted by geometrical factors.Key words Packing model Rhenium compounds Stability Normaliged“Van der waals”radii
