چکیده
The asymmetric unit of the title compound, [Pd(2)(C(9)H(12)NSe)(2)Cl(2)]·0.5CH(2)Cl(2), contains two half-mol-ecules, each lying on a twofold axis; each mol-ecule is chiral and of the same enanti-omer. This is only possible as the mol-ecule has a hinged cis arrangement about the Pd(2+) coordination spheres. For this hinged dimeric structure, the angles between the two coordination planes in each mol-ecule are 15.02 (5) and 14.91 (5)°. This hinged cis arragement also allows the two mol-ecules to form pairs linked by secondary inter-actions between the Pd and Se atoms [3.4307 (9) and 3.4317 (9) Å] of adjoining mol-ecules, leading to an overall tetra-meric structure. During the refinement stages, it was noticed that there were dichloromethane solvent mol-ecules present disordered about a twofold axis. After unsuccessful attempts were made to model this, they were removed using SQUEEZE.

In the title complex, [Pd(2)Cl(4)(C(18)H(22)N(4))]·C(7)H(8), each of the two four-coordinated Pd(II) atoms is in a slightly distorted square-planar geometry, defined by one N atom from the ligand, two bridging Cl atoms and one terminal Cl atom. Inter-molecular C-H⋯π inter-actions between the pyrazole ring H atom and the toluene ring stabilize the crystal structure.

In the title compound, [Zn(2)Cl(4)(C(22)H(18)N(4))(2)]·2C(3)H(7)NO, the 1,3-bis-[(benzimidazol-1-yl)meth-yl]benzene ligand bridges two ZnCl(2) units, forming a centrosymmetric dinuclear mol-ecule. The Zn(II) atom shows a distorted tetra-hedral coordination within a Cl(2)N(2) donor set.

The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions,...

The title compound, [Bi(C(7)H(7))(2)(C(9)H(12)N)], was obtained by treating chlorodi(p-tol-yl)bis-muthane with o-lithio-N,N-dimethyl-benzyl-amine. An intra-molecular Bi⋯N nonbonding inter-action is observed in the distorted trigonal triaryl-bis-muth coordination of the title compound.
