Solventless isomerisation reactions: A crystallographic and thermomicroscopic investigation of some six coordinate RuCl₂L₂L′₂complexes

Solid-state cis–trans isomerization reaction of (η5-MeC5H4)W(CO)2P(OiPr)3I

“…This compares well with the data obtained for the 1 H NMR studies indicating that the PXRD technique can be used to monitor the kinetics of crystalline powdered materials. A similar correlation between 1 H NMR and PXRD kinetics data have been reported for the solid state isomerisation of six coordinate ruthenium complexes [17,18]. …”

“…The apparatus used to monitor single crystals by optical microscopy has been described previously [17]. A single crystal of 1 was placed on a transparent glass slide containing a thermocouple and the slide loaded into an enclosed chamber containing the aluminum heating block.…”

Organometallic chemistry in the melt phase

“…The thermal, unidirectional isomerization of the trans, trans, trans (ttt) isomer to the thermodynamic cis, cis, trans (cct) isomer of six coordinate ruthenium complexes, RuCl 2 (L) 2 (PR 3 ) 2 (L = CO, RNC) (Table 3 - 33), was investigated by PXRD and thermomicroscopy techniques [81]. The solvent-free conversion of the ttt to the cct is unidirectional, and no ccc isomer was detected.…”

trans-trans-trans-Bis(benzyl isocyanide-κC)dichlorobis(triphenylphosphine-κP)ruthenium(II) dichloromethane solvate

“…Single crystals suitable for diffraction have been obtained, but they contain dichloromethane. These crystals disintegrate upon heating to 318-328 K, consistent with loss of solvent (Horwood et al, 2003). In this report, the structural characterization of the solvated material is presented.…”

“…The title complex was prepared according to literature methods (Katsuki et al, 1994) and crystallized from a dichloromethane/diethyl ether solution to yield irregular yellow crystals. A spectroscopic analysis has been reported previously (Horwood et al, 2003).…”
