The affinity and the binding mode of two benzo[g]phthalazine compounds, functionalized with one or two 2-(imidazole-4-yl)-ethylamine groups, to DNA and RNA models have been evaluated by means of UV-Vis, fluorescence and circular dichroism (CD) spectroscopies in combination with viscometry and molecular dynamics. Both organic molecules bind strongly to all nucleic acid models via the intercalation mode in the duplex structure, especially compound 1. Intriguingly, 1 exhibits different emission responses depending on the base composition of duplex DNA/RNAs, which points out the possibility of using it as a base selective nucleic acid probe. Moreover, the acid-base behaviour of both compounds has been studied by pH-metric titrations and UV-Vis and emission fluorescence techniques to investigate the unexplored basicity of this type of compound. 1 behaves as a triprotic base whilst 2 is a diprotic base with the protonation of the benzo[g]phthalazine moiety occurring in the physiological pH range.

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)(2)](PF6)(2) ( [1] (PF6)(2); L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2′-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1](PF6)(2) was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)(CH3CN)(bpy)(2)](PF6)(2) ([2] (PF6)(2)), was formed. X-ray crystallographic data revealed that, in [2](PF6)(2), L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)(2) shows a unique haptotropic rearrangement in an acetonitrile solution.

The title compound, C14H12N4S, was synthesized by the condensation reaction of hydralazine and 2-acetylthiophene and during the reaction, a proton transfer from the imino nitrogen atom to one of the endocylic nitrogen atoms occurred. The compound crystallizes in the monoclinic crystal system with two independent molecules (molecules 1 and 2) in the asymmetric unit. In each molecule, there is a slight difference in the orientation of the thiophene ring with respect to phthalazine ring system, molecule 1 showing a dihedral angle of 42.51 (1)degrees compared to 8.48 (1)degrees in molecule 2. This implies an r.m.s deviation of 0.428 (1) angstrom between the two molecules for the 19 non-H atoms. The two independent molecules are connected via two N-H center dot center dot center dot N hydrogen bonds, forming dimers which interact by two bifurcated pi-pi stacking interactions to build tetrameric motifs. The latter are packed in the ac plane via weak C-H center dot center dot center dot pi interactions and along the b axis via C-H center dot center dot center dot N and C-H center dot center dot center dot pi interactions. This results a three-dimensional architecture with a tilted herringbone packing mode.
