چکیده
In the title salt, C(26)H(29)N(2) (+)·Br(-), which may serve as a precursor for N-heterocyclic carbenes, the imidazolidine ring adopts a twist conformation with a pseudo-twofold axis passing through the N-C-N carbon and the opposite C-C bond. The N-C-N bond angle [113.0 (4)°] and C-N bond lengths [1.313 (6) and 1.305 (6) Å] confirm the existence of strong resonance in this part of the mol-ecule. In the crystal, a C-H⋯Br inter-action is present. The dihedral angle between the biphenyl rings is 64.3 (2)° and the phenyl rings make angles of 76.6 (3) and 18.5 (3)° with the plane of the imidazolidine ring.

A new ruthenium complex, [RuBrCl(C(28)H(32)N(2))], has been synthesized and characterized by elemental analysis, (1)H NMR, (13)C NMR, IR-spectroscopy and a single-crystal X-ray diffraction study. The Ru atom in this complex is best described as having a considerably distorted octa-hedral coordination environment with the arene occupying three coordination sites. Two further coordination sites a...

The coordination geometry about the Pd centre in the title compound, [Pd(C(40)H(42)N(5))Cl], is approximately square-planar. The CNC pincer-type N-heterocyclic carbene ligand binds to the Pd atom in a tridentate fashion by the amido N atom and the two carbene atoms and generates two six-membered chelate rings, completing the coordination.

In the title compound, C(32)H(33)NO(6)S, the indole ring system makes dihedral angles of 62.78 (10) and 80.53 (8)°, respectively, with the phenyl and benzene rings. In the crystal, the mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. Between the chains, a weak aromatic π-π stacking inter-action [centroid-centroid distance = 3.831 (2) Å] is ob...
