Abstract

The structure of (1-phenyl-3-{2-[(2-aminoethyl)amino]ethylimino}-1-buten-1-olato-O,N,N’,N”) palladium(II) thiocyanate, [Pd(baden)]NCS, was solved by heavy-atom method and refined anisotropically ro R = 0.026 for 2 851 unique observed reflections. The title complex crystallizes in the Pc21b space group with a = 11.919(2), b = 14.061(2), c = 19.769(3)Å, Z = 8. The structure contains two symmetrical-independent molecules, each includes the palladium complex cation and thiocyanate anion. The cation formed by the baden ligand consists of one six-membered and two five-membered chelate rings and the phenyl ring. The coordination polyhedron around palladium is slightly distorted and puckered N3O square. The structure is held predominantly by electrostatic forces, but besides there are weak intermolecular hydrogen bonds among baden and thiocyanate nitrogens.
