(3R*,3′R*)-1,1′-Dimethyl-3,3′-biindoline-2,2′-dithione

Abstract

The (3R*,3′R*) configuration of the title compound, C18H16N2S2, (I), has been unambiguously elucidated by X‐­ray analysis. Mol­ecules of (I) have C2 symmetry to a good approximation and a strongly folded shape. The interplanar angle between the two halves of a mol­ecule is 67.11 (6)°.

Structural, Magnetic and Electrochemical Studies of a New Series of Macrocyclic Mononuclear and Binuclear Manganese(III) and Unusually Stable Manganese(II) Complexes

“…Selected geometrical parameters are given in Tables I and II. In the complex, the macrocycle provides four donors; two amine nitrogen atoms and two phenoxy oxygen atoms are coordinated in the equatorial plane at distances of 1.951 (6) attempt was made to model the disorder. Bond lengths within the basal plane have a rather small range and may be influenced by the Jahn-Teller [18] effect; otherwise, bond lengths and angles are comparable with reported values [19]. 18.0(3) and 9.1(2) , respectively.…”

Thionations Using a P4S10−Pyridine Complex in Solvents Such as Acetonitrile and Dimethyl Sulfone

“…In contrast, its N , N -dimethyl derivative has, due to work by Hino et al, been known since 1969 . The structure of this derivative has also been confirmed by X-ray crystallography . It should also be added that compound 23 is much more stable than its previously studied isomer 28 , which has a strong tendency to undergo dimerization…”

“…82 The structure of this derivative has also been confirmed by X-ray crystallography. 83 It should also be added that compound 23 is much more stable than its previously studied isomer 28, which has a strong tendency to undergo dimerization. 84 Benzaldehyde has been thionated many times in the past, 85-90 and the product has invariably been isolated as the trimer (30) of the unstable primary product 29 (Figure 6), and the trimer 30, was indeed the product when benzaldehyde was reacted with the reagent 3 in dimethyl sulfone.…”

Controlled Redox Conversion of New X-ray-Characterized Mono- and Dinuclear Heptacoordinated Mn(II) Complexes into Di-μ-oxo-dimanganese Core Complexes

“…In the first two X-ray-characterized [Mn II (μ-OAc)Mn II ] 3+ core complexes, , the acetate anion presents a syn − anti bridging mode, leading to shorter Mn···Mn separations (5.67 and 4.82 Å) than the one reported here (6.341(3) Å) . Indeed, comparable Mn···Mn separations of 6.036, 6.335, and 6.555 Å are observed in 3D-structure systems where two Mn(II) ions are linked by a carboxylate group in the anti − anti conformation. When compared to the Mn···Mn separations (6.48−6.52 Å) observed in linear polymeric Mn(III) chains where the anti − anti bridging mode of the acetate ion is found, − the 6.341(3) Å Mn···Mn distance determined here is slightly shorter.…”
