Heterometallic Mercury Compounds: Classification and Analysis of Crystallographical and Structural Data

“…Figure 9. View of Hg g Co 6 (CO) 18 [142] Examination of the data for the heterometallic Hg clusters shows the mean The values below 300 pm indicate a metal-metal bond, and illustrate the ability of Hg to bond to both transition metal and non-transition metal atoms to create a wide range of cluster compounds.…”

“…orOs [146]) and HgOs 20 [139]. The molecular structure of the [Ru 18 Hg 3 C 2 (CO) 42 ]" 2 anion is shown in Figure 10, consisting of two tricapped octahedral nona-ruthenium subclusters fused by a bi-facecapping (Hg 3 ) +2 unit. Figure 9.…”

“…Of the sixteen CO groups about each Ru 6 unit, twelve are terminally bonded and four form asymmetric bridges. The structure of another red bimetallic cluster Hg g Co 6 (CO) 18 [141] is shown in Figure 9. The metal framework is a rectangular trigonal prism with the Co atoms at each corner and a Hg atom at the midpoint of each edge.…”

“…The Etjdtc ligands asymmetrically chelate the mercury atoms. The mean Hg-Nb distance of 279.0 ( 13,18) pm is indicative of a metal-metal bond, with the mean Hg-Hg distance being 289.2 (9,9) pm. Here, the first number in parenthesis is the low range variation from the mean, and the second number is the high range variation from the mean.…”

Preparative and Vibrational Spectroscopic Studies of Anilinium Salts Containing the [Hg2Cl6]2-, [Hg2Cl4X2]2-, [CdHgI6]2-, [CdHgI4Br2]2- and [CdHgBr4I2]2- Ions (X = Br, I)

“…the synthesis and spectroscopic characterization of salts containing the anions [Hg2Cl4X2]2~ (X = Br, I), [CdHgI6]2~, [CdHgI4Br2]2_ and [CdHgBr4I2]2~; we also report here the preparation and study of a salt containing the [Hg2Cl6]2-ion. In the past we [13,14], and oth ers [11,[15][16][17][18][19][20][21][22], have reported the reactions of M X, (M = Cd, Hg; X = Cl, Br, I) with X" to give anions of various degrees of condensation.…”
