The title compound, C4H6N2O, displays two predominant hydrogen-bonding inter-actions in the crystal structure. The first is between the unprotonated imidazole N atom of one mol-ecule and the hy-droxy H atom of an adjacent mol-ecule. The second is between the hy-droxy O atom of one mol-ecule and the imidazole N-H group of a corresponding mol-ecule. These inter-actions lead to the formation of a ...

The design of an efficient pure blue emitter to achieve stable, long operating organic light-emitting diode (OLED) devices still poses a significant challenge. Although through phosphorescence and thermally activated delayed fluorescence concepts, stable monochrome green red OLEDs can be realized, the has been All efforts so far have resulted in severe efficiency roll-off limited device lifetim...

In the title compound, C(22)H(21)BrN(4)O(2)·H(2)O, the two pyrazole rings are essentially planar [maximum deviations 0.002 (1) and 0.002 (1) Å], and form a dihedral angle of 73.46 (9)°. The dihedral angle between the benzene rings is 29.33 (7)°. In the crystal, mol-ecules are connected via C-H⋯O and O-H⋯N hydrogen bonds, forming layers in the ab plane.

In the title compound, [Zn(C(11)H(9)N(6))(2)](n), the Zn(II) atom lies on an inversion center and is coordinated by four N atoms from four 5-[4-(1H-imidazol-1-ylmeth-yl)phen-yl]tetra-zolate ligands in a distorted tetra-hedral geometry. The ligands bridge the Zn(II) atoms, leading to the formation of a two-dimensional network parallel to (010). The structure is further stabilized by C-H⋯N, C-H⋯π...

In the title compound, [MnCl(2)(C(11)H(13)N(5))], the Mn(II) ion is five-coordinated in a distorted square-pyramidal geometry, with three N atoms from the neutral tridentate 2,6-bis-(4,5-dihydro-1H-imidazol-2-yl)pyridine ligand and one chloride ion forming the basal plane and the other chloride ion in the apical position. Both dihydro-imidazole rings adopt envelope conformations. In the crystal...
