Tetrathiovanadate(V) and tetrathiorhenate(VII): structures and reactions, including characterization of the VFe2S4 core unit

[Me8Pt4ReS4]− and related PtMe2-containing clusters derived from tetrathiorhenate

“…1). At 2.12 Å , the terminal Re@S bonds are shorter than the Re-l-S bonds (2.19 Å ) but match those in Bu 4 N[ReS 4 ] [8]. The Pt-Re distance of 2.72 Å is clearly within bonding distance, consistent with Pt !…”

“…Re bonding. The S-Re-S angles are only slightly distorted compared to those in Bu 4 N[ReS 4 ] (107.4-112.8) [8]. The IR spectrum of 1 consists of a pair of intense bands near 500 cm À1 assigned as m Re@S (510, 498 cm À1 ); another band at 458 assigned to m Re-l-S .…”

Kinetics of the Reactions between [(RS)2Fe(µ-S)2M(µ-S)2Fe(SR)2]n− (M = Mo, R = Ph, n = 2; M = V, R = Et, n = 3) and [Fe(SR)4]2−: Key Steps in the Assembly of Cuboidal Fe—S-based Clusters

“…½ðEtSÞ 2 Feðl-SÞ 2 Vðl-SÞ 2 Fe(SEt) 2 3À has not previously been reported but the electronic spectrum of the MeCN solution produced {k max /nm (e/dm 3 mol )1 cm )1 ): 425 (15,000); 522 (10,800)} is very similar to that of ½Cl 2 Feðl-SÞ 2 Vðl-SÞ 2 FeCl 2 3À {k max /nm (e/dm 3 mol )1 cm )1 ): 396 (5500); 516 (6400)} [7] and ½ðPhSÞ 2 Feðl-SÞ 2 Vðl-SÞ 2 Fe(PhS) 2 3À {k max /nm (e/dm 3 mol )1 cm )1 ): 428 (15,100); 533 (11,400); 572 (shoulder)} [7].…”

“…½NEt 4 3 ½Cl 2 Feðl-SÞ 2 Vðl-SÞ 2 FeCl 2 was prepared by a method analogous to that described in the literature [7]. [7].…”
