“…As part of our activity during the last years, we have presented complexes possessing antiproliferative activity, [5][6][7] technologically important optical properties, 8 and catalytic activity, [9][10][11] including the ability to catalyse the isomerization of allylic alcohols under mild conditions in water. 12 The activity of the catalytic species responsible for the isomerization of linear allylic alcohols [RuCp(H2O-κO)(PTA)2](CF3SO3) (1•CF3SO3) 13 (Scheme 2) is strongly influenced by the presence of water in the reaction (PTA = 1,3,5-triaza-7-phosphaadamantane).…”

We describe the intermediate of the reaction between a ruthenium complex and the 1-propen-3-ol in water by an atomistic approach for gaining information about the conformation and dynamics of complex molecules in aqueous solution, which combines DFT based ab initio molecular dynamics (AIMD) and neutron scattering data based on Empirical Potential Structure Refinement (EPSR) simulations. We apply our method to the study of the water soluble h 2-allylic complex [RuCp(exo-h 2-CH2=CH-CH2-OH)(PTA)2] + (2) (PTA = 1,3,5-triaza-7-phosphaadamantane), a significant intermediate in the isomerisation of 1-propen-3-ol into propanal catalysed by {RuCp(H2O-κO)(PTA)2} +. We identify the factors responsible for the stabilisation of a specific conformer of 2 in water solution and, for the first time, we demonstrate the direct involvement of water molecules in the formation of this species. In particular, we show that long-lived (ca. 10 ps) bonded chains of water molecules play a crucial role in influencing the conformation and, potentially, the chemical reactivity of 2.

“…It should be noted that this approach is believed to be promising as it brings a new perspective to the synthesis of organometallic polymers. 70 The dithiol toolbox was also examined to explore the scope of the polymerization, and BA was used as the model aldehyde in these studies. Similar to P1, PDTAs of high M n s were observed when linear aliphatic dithiols such as 1,4-butane-dithiol (P13, M n = 66 kDa) and 1,8-octanedithiol (P14, M n = 58 kDa) were used in the polymerization reactions.…”

Amorphization of a Ru‐Ru‐Cd‐Coordination Polymer at Low Pressure

The water soluble backbone heterometallic polymer {[{(PTA)2CpRu‐µ‐CN‐RuCp(PTA)2}‐µ‐CdCl3]}n (1), which is easily obtained in large amount, was synthesized and its structure determined by single crystal X‐ray diffraction. Coordination‐polymer 1 becomes amorphous when milled under low pressure (0.5 MPa). The amorphous compound was characterized by MAS‐NMR, elemental analysis, TG and Raman spectroscopy. The Raman spectrum of the coordination polymer was assigned by comparison with the Raman spectrum obtained by DFT calculation of a simple model of 1. The analysis of both calculated and experimental Raman spectra showed that Raman spectroscopy can be used to determine if the PTA ligand is mono‐ or bidentate, giving rise to a method for characterization and future studies of polymeric complexes containing bidentate PTA. The phase transformation of 1 under pressure and temperature was studied by PXR, showing how is possible to model easily this Ru‐Ru‐Cd inorganic polymer into a variety of different solid forms with possible new properties.
