In the title compound, [Mn(C(5)H(6)N(3)O)(2)(C(3)H(7)NO)]ClO(4), the Mn(III) atom lies on the inversion centre of the centrosymmetric complex cation and has a distorted octa-hedral coordination geometry, formed by two N atoms and two O atoms from two 1-methyl-imidazole-2-carbaldehyde oximate ligands and two O atoms from two dimethyl-formamide ligands. Perchlorate acts as a counterion to balance...

The article describes the synthesis and extraction properties of the new hexahomotrioxacalix[3]arenebased derivatives cone- and partial-cone-2 bearing 1-methyl-1H-imidazole moieties at the lower rim. It has been demonstrated that O-alkylation of the flexible macrocycle 1 with 2-(chloromethyl)-1-methyl-1Himidazole hydrochloride affords tri-O-alkylated products with a cone or partial-cone conform...

In the title complex, [Co(C(4)H(6)N(2))(2)(H(2)O)(4)](C(10)H(6)O(6)S(2)), the cation and anion both reside on crystallographic inversion centers, such that the asymmetric unit comprises one half cation and one half anion. The central Co(II) ion is coordinated by four water mol-ecules and two 2-methyl-imidazole ligands, resulting in a trans-octa-hedral coordination geometry. The existence of str...

Since C^C* cyclometalated Pt(II) complexes with N-heterocyclic carbene (NHC) ligands have been identified as potential emitter materials in organic light-emitting devices (OLEDs), very promising results regarding quantum yields, colour and stability have been presented. Herein, we report on four nitrile substituted complexes with a chelating NHC ligand (1-(4-cyanophenyl)-3-isopropyl-1H-benzo[d]...

The asymmetric unit of the title compound, C14H10N2O2, contains two independent mol-ecules. In each mol-ecule, the benzodioxole ring system displays an envelope conformation, with the methyl-ene C atom located at the flap deviating by 0.081 (2) and 0.230 (2) Å from the mean plane formed by the other atoms. The dihedral angles between the benzo-imidazole ring system (all atoms) and the benzodiox...

The title compound, [Zn(C(8)H(4)O(4))(C(5)H(8)N(2))(3)], has a neutral monomeric structure in which one terephthalate dianion and three 2-ethyl-1H-imidazole ligands coordinate to the Zn(II) ion in a distorted tetra-hedral geometry. The methyl group of one of the ethyl groups is disordered over two positions with occupancies of 0.66 (2) and 0.34 (2). In the crystal structure, mol-ecules are link...

The title compound, C19H17Cl3N2O3, has been prepared in a cyclo-condensation reaction between 2,3,5-tri-chloro-benzaldehye and 4-acetyl-2-methyl-1H-imidazole. The cyclo-hexenone ring adopts an envelope conformation with the C atom substituted by the tri-chloro-phenyl ring as the flap. The mutually trans ester and aryl substituents both occupy equatorial sites. In the crystal, a combination of N...

The asymmetric unit of the title compound, [Co(C(4)H(6)N(2))(6)]Br(2)·2H(2)O, contains one-half of the centrosymmetric cation, one Br atom and one water mol-ecule. The Co(II) atom, lying on an inversion center, has a distorted octa-hedral geometry, defined by six N atoms from six 1-methyl-imidazole ligands. In the crystal structure, intra- and inter-molecular O-H⋯Br hydrogen bonds link pairs of...

In the title compound, [Co(C(12)H(9)O(2))(2)(C(4)H(6)N(2))(2)(H(2)O)(2)], the Co(II) ion is located on an inversion centre and displays a distorted octa-hedral coordination geometry. Two O atoms from two water mol-ecules and two carboxyl-ate O atoms from two 2-(naphthalen-1-yl)acetate ligands are in the equatorial plane and two N atoms from two 1-methyl-1H-imidazole ligands are in the axial pos...
