摘要

标题化合物的不对称单元[Co(C24H30N2P2)(Co)3][Co(Co)4]·0.25C7H8，由两个具有相似构象的晶体独立的阳离子、两个阴离子和半个围绕反转中心紊乱的甲苯分子组成。在阳离子中，Co/P/N/P四元微弯曲金属环是关键的结构元素。悬垂的NH基团不与Co(I)原子配位，表现出扭曲的三角-双锥体配位几何。在四面体[Co(Co)4](-)阴离子的NH基团和羰基之间观察到弱的离子间氢键。

Crystal structure of tricarbon-yl(N-di-phenyl-phosphanyl-N,N'-diisopropyl-P-phenyl-phospho-nous di-amide-κ(2) P,P')cobalt(I) tetra-carbonyl-cobaltate(-I) toluene 0.25-solvate.

The asymmetric unit of the title compound, [Co(C24H30N2P2)(CO)3][Co(CO)4]·0.25C7H8, consists of two crystallographically independent cations with similar conformations, two anions, and one-half of a toluene mol-ecule disordered about an inversion centre. In the cations, a Co/P/N/P four-membered slightly bent metallacycle is the key structural element. The pendant NH group is not coordinated to the Co(I) atom, which displays a distorted trigonal-bipyramidal coordination geometry. Weak inter-ionic hydrogen bonds are observed between the NH groups and a carbonyl group of the tetrahedral [Co(CO)4](-) anions.

期刊介绍： Acta Crystallographica Section E: Structure Reports Online is the IUCr highly popular open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal structure determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indicators and validation reports provide measures of structural reliability. In 2009, the journal published over 4000 structures. The average publication time is less than one month.
