Two isomers of Pd2(S2NC7H4)4.
The dichloromethane solvates of the isomers tetrakis(mu-1,3-benzothiazole-2-thiolato)-kappa(4)N:S;kappa(4)S:N-dipalladium(II)(Pd-Pd), (I), and tetrakis(mu-1,3-benzothiazole-2-thiolato)-kappa(6)N:S;kappa(2)S:N-dipalladium(II)(Pd-Pd), (II), both [Pd2(C7H4NS2)4] x 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.
