Source of material

Fe3(CO)12 (0.050 g, 0.10 mmol), Na2Te2 (0.045 g, 0.15 mmol), and PPNCl (0.345 g, 0.60 mmol) were charged to a Pyrex tube with diameter of 9 mm under an argon atmosphere and about 0.4 mL MeOH was added as a solvent. While the solvent was being frozen, the Pyrex tube was evacuated under vacuum and sealed with the use of a flame. The sealed tube was placed in an oven and heated at 80 °C for a day, then cooled to room temperature. Dark red block crystals were isolated by filtration and washed with MeOH and diethyl ether several times. Crystals of (PPN)2[Fe5Te4(CO)14] were obtained in 26% yield, based on the Fe metal used.

Comment

Iron carbonyl teluride clusters have attracted attention a lot especially for their structural novelty and diversity [5], [6], [7], [8], [9]. Hitherto known homometallic anionic iron tellurido carbonyl clusters are as follows: [Fe2Te3(CO)6]2− [6, 7], [Fe4Te2(CO)14]2− [8], [Fe5Te4(CO)14]2− [9], [Fe6Te14(CO)12]2− [7], and [Fe8Te10(CO)20]2− [9]. The cation adopted to stabilize the homometallic anionic iron tellurido carbonyl clusters has been limited to Ph4P+ only except (K⋅crypt)+ for [Fe2Te3(CO)6]2−. Here we report another homometallic iron tellurido carbonyl cluster compound stabilized with bis(triphenylphosphine)iminium, PPN+ cations. By employing a methanothermal method, (PPN)2[Fe5Te4(CO)14] has been synthesized from the reaction between Fe3(CO)12 and Na2Te2 in the presence of PPNCl. It is noteworthy that (Ph4P)2[Fe5Te4(CO)14] had been synthesized by the solution method, from the reaction between a fivefold excess of [Fe(CO)5] and (Ph4P)2Te4 in DMF at 85 °C [9].

The [Fe5Te4(CO)14]2− anion in (PPN)2[Fe5Te4(CO)14] was revealed to be of the same molecular structure as the one in the (Ph4P)2[Fe5Te4(CO)14]. The molecular structure of the [Fe5Te4(CO)14]2− anion could be divided into three fragments, that is, a Fe(CO)2 central fragment and two Fe2Te2(CO)6 side fragments. The Fe2Te2(CO)6 side fragment shows a so-called ‘butterfly’ structure which is often encountered in other iron carbonyl chalcogenide compounds [10, 11]. There exists a metal-metal bond in each Fe2Te2(CO)6 side fragment, as the Fe(2)–Fe(3) and Fe(4)–Fe(5) bond distances are 2.602(1) and 2.606(1) Å, respectively, which are quite similar to the Fe–Fe bond distance of 2.592(4) Å in the (Ph4P)2[Fe5Te4(CO)14]. The Te(1)–Te(2) and Te(3)–Te(4) distances are 3.1342(4) and 3.1454(4) Å, respectively, which are also quite similar to the Te–Te distance of 3.152(2) Å in the (Ph4P)2[Fe5Te4(CO)14]. As the Te–Te distances of these lengths are too long to be assigned as those of ditelluride, Te2 2− ions, which are normally in the range of 2.7–2.8 Å, each butterfly iron atom is supposed to possess the oxidation state of +1. Considering the oxidation state of +2 in the central Fe atom, the charge valence of the [Fe5Te4(CO)14]2− anion could be described as [(Fe+2)(Fe+1)4(Te−2)4(CO)14]2−.
