The syntheses, spectroscopic and structural characterizations of the first iron and copper thiolate guanidine complexes are described. Reactions of the neutral complexes [CuI(btmgp)] and [FeI2(btmgp)] [btmgp = 1,3-bis(N,N,N′,N′-tetramethylguanidino)propane] with different uni- and bi-dentate thiolate ions yield the three-coordinate complex [Cu(S-2,4,6-tBu3C6H2)(btmgp)] (1) and the four-coordinate complexes [Fe(S-2,4,6-iPr3C6 H2)2(btmgp)] (2) and [Fe(SiMe2(C6H4S)2)(btmgp)] (3) respectively. Starting with [Fe(N(SiMe3)2)2], btmgp and the dithiol SiMe2(C6H4SH)2, an alternative procedure for the preparation of 3 is reported, demonstrating a useful synthetic approach towards neutral, N/S mixed coordinated Fe(II) complexes. The X-ray structure analyses of 1-3 reveal trigonal planar (2N/1S) (1) and tetrahedral (2N/2S) (2, 3) coordination environments around the metal centers.
