AB  - The reactions of ruthenium(II)-arene complex [Ru-II(eta(6)-p-cym)(pydc)Cl] (where p-cym = p-isopropyl toluene, pydc = 2,3-pyridinedicarboxylato) with biologically nitrogen-donor nucleophiles, such as guanosine-5'-monophosphate (5'-GMP), guanosine (Guo) and L-histidine (L-His) were studied by UV-Vis spectrophotometry and H-1 NMR spectroscopy. The reactions were studied at pH 2.5 and at 7.2. All reactions were followed under pseudo-first order conditions with large excess of the nucleophiles. The selected nucleophiles have a high affinity for Ru(II)-arene complex. The reactivity of the used ligands follow the same order at both pH values: Guo  gt  5'-GMP  gt  L-His, while the reactions at pH 7.2 are always faster. The negative entropies of activation (Delta S-not equal) support an associative mode of activation. However, the rate constants obtained by H-1 NMR at 295 K in D2O follow the same order of the ligand reactivity. The hydrolysis of the [Ru-II(eta(6)-p-cym)(pydc)Cl] complex was very fast and completed by the time the first spectrum was measured. Addition of excess of NaCl to equilibrium solutions reversed the hydrolysis. (C) 2011 Elsevier Ltd. All rights reserved.

AB  - Stacking interactions of terpyridyl square-planar complexes in crystal structures were studied analyzing data from the Cambridge Structural Database. In most of the crystal structures, two terpyridyl complexes were oriented "head-to-tail" or "head-to-head", with "head-to-tail orientation" being most prevalent. The number of structures with other orientations was very small. Based on the analysis of interacting geometries, we classified overlaps of terpyridyl complexes into six types. The types were defined by values of several geometrical parameters and all interactions of the same type had very similar overlap patterns.
