Bis{μ-2-[(dimethyl­amino)­meth­yl]benzene­seleno­lato}bis­[chloridopalladium(II)] dichloromethane hemisolvate

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-mol­ecules, each lying on a twofold axis; each mol­ecule is chiral and of the same enanti­omer. This is only possible as the mol­ecule 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 mol­ecule are 15.02 (5) and 14.91 (5)°. This hinged cis arragement also allows the two mol­ecules to form pairs linked by secondary inter­actions between the Pd and Se atoms [3.4307 (9) and 3.4317 (9) Å] of adjoining mol­ecules, leading to an overall tetra­meric structure. During the refinement stages, it was noticed that there were dichloromethane solvent mol­ecules present disordered about a twofold axis. After unsuccessful attempts were made to model this, they were removed using SQUEEZE.
