Two isomers of Pd₂(S₂NC₇H₄)₄

The dichloro­methane solvates of the isomers tetra­kis([mu]-1,3-benzothia­zole-2-thiol­ato)-[kappa]⁴N:S;[kappa]⁴S:N-dipalladium(II)(Pd-Pd), (I), and tetra­kis([mu]-1,3-benzothia­zole-2-thiol­ato)-[kappa]⁶N:S;[kappa]²S:N-dipalladium(II)(Pd-Pd), (II), both [Pd₂(C₇H₄­NS₂)₄]·CH₂Cl₂, have been synthesized in the presence of (o-isopropyl­phen­yl)­diphenyl­phosphane and (o-methyl­phen­yl)­diphenyl­phosphane. Both isomers form a lantern-type structure, where isomer (I) displays a regular and symmetric coordination and isomer (II) an asymmetric and distorted structure. In (I), sitting on an centre of inversion, two 1,3-benzothia­zole-2-thiol­ate units are bonded by a Pd-N bond to one Pd atom and by a Pd-S bond to the other Pd atom, and the other two benzothia­zole­thiol­ate units are bonded to the same Pd atoms by, respectively, a Pd-S and a Pd-N bond. In (II), three benzothia­zole­thiol­ate units are bonded by a Pd-N bond to one Pd atom and by a Pd-S bond to the other Pd atom, and the fourth benzothia­zole­thiol­ate unit is bonded to the same Pd atoms by, respectively, a Pd-S bond and a Pd-N bond.
