Abstract

The coordination geometry of the Pd atom in the title compound, [Pd(SCN)(2)(C(46)H(54)N(4)O(6))], is approximately square-planar. The N-heterocyclic carbene (NHC) metallacrown ether ligand binds to the Pd atom in a trans orientation through the carbene C atoms of the two imidazole rings and generates a 25-membered chelate ring. Two mutually trans S-bound thio-cyanate ligands complete the coordination.
