Synthesis and characterization of ferrocenyl and bis(ferrocenyl) alkynes and polyynes: crystal structure of 1,4-bis(ferrocenyl)butadiyne and third order nonlinear optical properties of 1,8-bis(ferrocenyl)octatetrayne

Synthesis, Crystal Structures and Third‐Order Nonlinear Optical Properties of Two Novel Ferrocenyl Schiff‐Base Complexes [Ag(L)2](NO3)⋅(MeOH)⋅(EtOH) and [HgI2(L)] {L = 1,2‐Bis[(ferrocen‐l‐ylmethylene)amino]ethane}

“…The γ values of our complexes are also similar to those of the ferrocenyl complexes 1,8-bis(ferrocenyl)octatetrayne [32] and NiL . [33] To our knowledge, there have been no reports on third-order NLO properties of diferrocenyl Schiffbase complexes.…”

Ferrocenylsubstituierte Metallacyclen des Titanocens – Oligocyclopentadienylkomplexe mit vielversprechenden Eigenschaften

“…[10] Mach et al wiederum beschreiben Titanocenkomplexe der monoferrocenylsubstituierten Alkine FcCCR (R = SiMe 3 , Ph), die vollständig charakterisiert wurden. [11] Hier stellen wir die Synthese, Struktur und elektrochemischen Eigenschaften der Verbindungen 1 und 2 vor, die formal durch die Addition von Titanocenfragmenten an Diferrocenylacetylen (FcCCFc) [12] oder 1,4-Diferrocenylbuta-1,3-diin (FcCCCCFc) [13] entstehen. Deren physikalische und chemische Eigenschaften wurden intensiv untersucht und mit den Ergebnissen aus quantenchemischen Rechnungen untermauert.…”

Heterobimetallic Fe–Pd and Fe–Pt NCN pincer complexes (NCN=[C6H2(CH2NMe2)2-2,6]−)

“…The main molecular features of 8 and 13 resemble the structural data, characteristic for ferrocene and NCN pincer complexes [2,15]. The asymmetric unit of crystals of 8 contains two molecules of 8, having similar bond distances and bond angles.…”

“…3 is discussed. As characteristic for other ferrocene complexes the Fe1-D1 and Fe1-D2 separations (D1, D2 = centroids of the cyclopentadie- Table 1 Electrochemical data of 2, 3, 5, 7, 8 and 11-13 (2) nyl ligands C 5 H 4 and C 5 H 5 , respectively) are found with 1.641(2) and 1.639(3) Å for 8 and 1.634(3) Å for 13 [15]. The two cyclopentadienyl ligands are thereby rotated by À12.2(4)°8 or 2.5(5)°13 with respect to each other, which verifies an almost eclipsed conformation.…”
