Cymantrenecarboxylate complexes of nickel(II) and cobalt(II)

Supramolecular interactions in the structures of carboxylate derivatives of cymantrene and single-charged cations

“…In the structures of cymantrenylcarboxylate complexes of transition metals, the L À ligands also behave similarly to other carboxylates [43,44]. It has been shown for the structures studied in this paper that the cymantrene moiety in L À and L 1À can participate both in metal coordination through CO groups (compounds III and IV) and in formation of HBs as a hydrogen donor (the Cp moiety) and hydrogen acceptor (the oxygen atoms of the CO groups), which is a specific feature of cymantrenecarboxylate derivatives.…”

Binuclear and polynuclear cymantrenecarboxylate complexes of heavy lanthanides

“…These complexes are binuclear, which is typical of rare earth metal carboxylates [6][7][8][9][10]. In the structures of the transition metal cyman trenecarboxylate complexes, the O 2 CCym ligands (Cym is (η 5 C 5 H 4 )Mn(CO) 3 ) also behave similarly to other carboxylates [11][12][13][14]. However, in the case of lanthanides of the yttrium group, binuclear cyman trenecarboxylates were synthesized only when dime thyl sulfoxide (DMSO) was used as an additional ligand.…”

Synthesis and Reactivity of Bis(6‐diphenylphosphinoacenaphth‐5‐yl)ditelluride

“…The investigated specimen of 3 crystallized in the orthorhombic Sohncke space group P2 1 2 1 2 1 , [17] which lacks an inversion center and is therefore chirodescriptive. [18] [22] 2.617(1) 1.753(4) a) 1.713(1) CpMn(CO) 2 PhTeFe(PPh 3 )Cp [14] 2.600(1) 1.737 (7) 2.216(2) 1.729(1) Sum of the van der Waals radii [24] 2.70 2.01 2.39 a) Mean value. The unit cell contains only one of the two enantiomers of 3, the configuration of which was unambiguously determined by refinement of the Flack parameter [0.001(8)] [19] Therefore, we hypothesize that upon crystallization of 3 a spontaneous resolution had taken place, which separated the racemate into a conglomerate of enantiopure crystals.…”
