Etude structurale du bromure de tris(éthylènediamine)chrome(III) 0,6 hydraté, (+)-[Cr(en)3]Br3.0,6H2O

Abstract: The structure can be described as consisting of complex-ion layers P(1) P(2) P(1)...; P(1) layers are formed by a lattice of elementary pentagonal and triangular figures. The ieosahedral holes defined by this stacking are occupied by the other complex ions lying in P(2) layers. The same type of arrangement can be observed in three dimensions and so confers a pseudocubic character on this orthorhombic structure. IntroductionS'il existe une isotypie totale (maille commune trigonale subissant peu de variations de… Show more

“…Thus, the number, kind and strength of hydrogen bonds formed by [Co(1)(en)3 ]3+ differs from that formed by [Co(2)(en)3] 3+. A common feature for both is that iodide anions are bonded to -NH(ob) groups, in agreement with the steric criterion of Raymond, Corfield & Ibers (1968) developed by Spinat, Whuler & Brouty (1979). On the other hand, it can be assumed that the presence of four base sites in the planar oxalate anions makes possible the stabilization of A666 or A222 configurations instead of other configurations, such as A2,;t2 or A66~, which are usually stabilized when an extensive hydrogen-bonding network exists (Haque, Caughlan & Emerson, 1970;Duesler & Raymond, 1971;Cramer & Huneke, 1978).…”
