In the title compound, [Pt(C17H19N4)Cl], the Pt(II) cation is C,C',C''-chelated by the 1,1'-(5-methyl-1,3-phenyl-ene)bis-(3,5-dimethyl-1H-imidazolyl-idene) anion and coordinated by a Cl(-) anion in a distorted square-planar coordination geometry. π-π stacking is observed between nearly parallel imidazole and benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.802 (4) Å.

In the present research work, evaluation of a non-ionic gemini surfactant derived from palm oil named bis(2-((2-palmitoamidoethyl) amino) ethyl) 1H-imidazole-4,5-dicarboxylate as an ecological corrosion inhibitor X100 steel immersed in NaCl solution at 3.5% saturated with carbon dioxide (CO 2 ) was analyzed. The electrochemical tests performed by Polarization Curves (PC) and Electrochemical Imp...

The management of proton conductivity in the protic ionic liquid imidazolium bis(trifluoromethylsulfonyl)imide ([Im][TFSI]) is investigated via the use of quasi-elastic neutron scattering (QENS) and pulsed-field gradient NMR. The introduction of excess neutral imidazole to [Im][TFSI] leads to enhanced conductivity. We find that proton dynamics in [Im][TFSI] with excess imidazole are characteriz...

In the title compound, C(12)H(16)N(4) (+)·2C(7)H(4)NO(4) (-), the complete 2,2'-(p-phenyl-ene)bis-(4,5-dihydro-1H-imidazol-3-ium) (bib) dication is generated by crystallographic inversion symmetry. The bib cations reside on crystallographic inversion centers, which coincide with the centroids of the respective benzene rings. In the cation, the imidazole ring adopts an envelop conformation with ...

O(6)-Benzylguanine (BG) effectively inactivates the DNA repair protein O(6)-alkylguanine-DNA alkyltransferase and enhances the effectiveness of alkylating agents, such as 1,3-bis(2-chloroethyl)-1-nitrosourea and temozolomide, in vitro and in vivo. BG is presently in clinical trials with 1,3-bis(2-chloroethyl)-1-nitrosourea and temozolomide. Preclinical data demonstrate that BG enhances the sens...

In the title complex, [Co(C(12)H(8)N(4)O(8))(H(2)O)(2)], the Co(II) atom is coordinated by two N and two O atoms of the tetra-dentate 5,5'-dicarb-oxy-2,2'-(ethane-1,2-di-yl)bis-(1H-imidazole-4-carboxy-l-ate) anion. The slightly distorted octa-hedral coordination environment is completed by the O atoms of two water mol-ecules in axial positions. An intra-molecular O-H⋯O hydrogen bond between the...
