1‐D Polymeric Iron(II) Thiolato Complexes: Synthesis, Structure, and Properties of _∞¹[Fe(SR)₂] (R = Ph, Mes), _∞¹[Fe(NH₃)(SPh)(µ‐SPh)] and _∞¹[(µ‐SPh)Fe(NH₃)₂(µ‐SPh)₂Fe(µ‐SPh)]

Abstract

The first examples of polymeric homoleptic iron(II) thiolato complexes ∞ 1 [Fe(SPh) 2 ] and ∞ 1 [Fe(SMes) 2 ] (Ph = phenyl = C 6 H 5 , Mes = mesityl = C 6 H 2-2,4,6-(CH 3 ) 3 ) have been both prepared by reaction of [{Fe(N(SiMe 3 ) 2 ) 2 } 2 ] with four equivalents of HSR ( R = Ph, Mes). In the crystal the two compounds form onedimensional chains with bridging thiolato ligands comprising distinctly different Fe-S-Fe bridging angles namely 75.20-75.25°in ∞ 1 [Fe(SPh) 2 ] and 91.38°in ∞ 1 [Fe(SMes) 2 ]. Reaction of ∞ 1 [Fe(SPh) 2 ] with stoichiometric amounts of NH 3 , generated by reaction of HN(SiMe 3 ) 2 with CH 3 OH, resulted in the formation [a]

Impact of substituent position on crystal structure and photoconductivity in 1D and 2D lead(ii) benzenethiolate coordination polymers

“…Mn 2+ , Fe 2+ , and Co 2+ ) often exhibit 1D architectures with 1D (–M–S–) n chains. 26–28 Conversely, S-CPs with d 10 coinage metal ions ( i.e. , Cu + , Ag + , and Au + ) undergo a (–M–S–) n dimensionality change depending on substituent species.…”
