Metal ion-aromatic complexes. VII. Crystal and molecular structure of bis(m-xylene)silver perchlorate

Crystal structure of a ternary mononuclear copper (II) complex: 4-chloro-3-methyl-6[(N-2-picolyl)-1′-iminomethyl]phenolato copper(II)perchlorate

“…The mean Cl-O bond length of 1.405(4)Å compares with the value of 1.43Å reported for well defined ClO 4 group [22]. The observed O-Cl-O bond angles (105-113°) are reasonably close to tetrahedral value and fall within the wide range generally found for ClO 4 groups [23].…”

A fluxional pseudo-Jahn-Teller complex: the structure of (acetato)bis(1,10-phenanthroline)copper(II) perchlorate, [Cu(C12H8N2)2(C2H3O2)]ClO4, at 298 and 173 K

“…(Frenz & Ibers, 1972) and with the weighted-mean values reported for molecular 1,10phenanthroline (Nishigaki, Yoshioka & Nakatsu, 1978). The mean CI-O bond lengths, 1-41 (298 K) and 1.42 A (173 K), compare favorably with the value of 1.43 A reported for well defined CIO4 groups (Taylor, Hall & Amma, 1969). The mean CI-O bond lengths, 1-41 (298 K) and 1.42 A (173 K), compare favorably with the value of 1.43 A reported for well defined CIO4 groups (Taylor, Hall & Amma, 1969).…”

Hydrogen/Deuterium Exchange Catalyzed by an Unusually Stable Mercury–Toluene Complex

“…[13] Although the Kochi complex was the first (and only) crystallographically characterized mercury ± arene p complex prior to our work, several examples have been spectroscopically characterized. [14,15] Of note is the isostructural relationship of 1 to the reported [Ag(C 6 H 4 Me 2 ) 2 (ClO 4 )] complex, [16] in which the arene rings in the silver complex are also bound in an asymmetric h 2 manner. It was proposed that the perchlorate group played a significant role in stabilizing the Ag I -aromatic complex and the [GaCl 4 ] À ion clearly performes a simmilar function with the mercury.…”
