Heterocyclen als Liganden, XI. Octamethyl-1,1′-diazaferrocen als bifunktionelle Stickstoff-Base
TL;DR: In this article, the tetramethylpyrrole molecules were substituted with tetrameric pyrrole to give the adducts (C4Me4N·E)2Fe]n+ [4, 6, 11, 13, 14, 15, 16, 17, 18, 19, n = 2, EH, EC4me4NH, E'=Fe(CO)4; n = 1, EBH3, E´=H; n=2, E''E''H, EB''H', E''H''
Journal ArticleDOI
Synthesis, structure, and reactions of a dimeric rhodium(I) complex with bridging σ- and π-bonded 2,5-dimethylpyrrolido ligands
TL;DR: In this paper, the X-ray structure of the rh-carbonyl (1) complex was shown to be a square-planar rh 1 complex with two PPh 3 groups in trans positions and the remaining positions occupied by CO and a σ-bonded pyrrolide ion.
Journal ArticleDOI
Restricted Rotation in Unbridged Sandwich Complexes: Rotational Behavior of closo‐[Co(η5‐NC4H4)(C2B9H11)] Derivatives
TL;DR: Rotational energy barriers and the relative populations of the different energy states are calculated from 1H DNMR spectroscopy (DNMR, dynamic NMR).

Journal ArticleDOI
Metal complexes of heterocycles I. The preparation of pyrrolyl manganese and iron derivatives
TL;DR: Pyrrole and its alkyl derivatives react with manganese carbonyl giving (alkyl) pyrrolylmanganese tricarbonyls.
Journal ArticleDOI
Protonation of metal carbonyl complexes : III. Cyclopentadienyl carbonyl complexes of manganese
TL;DR: Using IR spectroscopy, the phosphine derivatives of cyclopentadienylmanganese tricarbonyl have been shown to undergo protonation in solutions of trifluoroacetic acid and in mixtures of this solvent with methylene chloride as discussed by the authors.
Journal ArticleDOI
Protonation of metal carbonyl complexes : I. An infrared study of the arenechromium tricarbonyl and arenechromium dicarbonyl triphenylphosphine complexes
TL;DR: In this article, the authors used IR spectroscopy to demonstrate the protonation of arenechromium dicarbonyl triphenylphosphine complexes in trifluoroacetic acid and in mixtures of the latter with methylene chloride.

TL;DR: The N-azacymantrene complex (η5-C5H5)Mn(L1)2L2 (L1 = 2; L2 = diphenylacetylacetato-O) is derived from the NMR spectra and has been proved by an X-ray structural determination for the crystalline state as discussed by the authors.
