Heterometallic cubane single-molecule magnets.
Two new heterometallic cubane molecules have been synthesized. High-frequency electron paramagnetic resonance and magnetization measurements indicate that [Mn(3)Ni(hmp)(3)O(N(3))(3)(C(7)H(5)O(2))(3)] (1) displays a well-isolated S = 5 ground state (DeltaE > 120 K), with g = 2.0, D = -0.23 cm(-1), and ferromagnetic Mn-Mn exchange interactions competing with antiferromagnetic Ni-Mn interactions. ...
متن کاملSodium cubane and double-cubane aggregates of hybridised salicylaldimines and their transmetallation to nickel for catalytic ethylene oligomerisation.
Deprotonation of functional salicylaldimines with NaH invariably results in cubane or double-cubane Na(I) aggregates which transmetallate with Ni(II) under different stoichiometric conditions to give Ni(II) complexes that are catalytically active towards ethylene oligomerisation.
متن کاملThe enthalpy of sublimation of cubane
13 The sublimation enthalpy of cubane, a key reference material for force field and quantum mechanical computations, was measured by combining the vaporization enthalpy at T = 298.15 K to the sum of the fusion enthalpy measured at T = 405 K and a solid–solid phase transition that occurs at T = 394 K. The fusion and solid–solid phase transitions were measured previously. A sublimation enthalpy v...
متن کاملCan cubane act as a benzene isostere?
The synthesis of cubane (1), achieved in 1964 by Eaton, was previously predicted to be impossible, due to the immense strain of the molecular structure. Since then a large array of chemical transformations have been performed on the cubane ring system demonstrating the framework to be both a stable and robust building block. Considering the geometry of cubane (1), it is noteworthy that the dist...
متن کاملPossible Orientationally Ordered States of Bucky-Cubane
For temperatures above T∗ = 130K C60⋅C8H8 forms a cubic crystal consisting of two interpenetrating fcc sublattices, one of freely rotating Buckys C60 and the other of orientationally ordered cubane C8H8. The crystal structure below a discontinuous transition is found to be orthorhombic, but the nature of the ordering of the Buckys has not yet been determined. Here possible orderings of the Buck...
