Direct Observation of the Luminescence from the ³δδ* Excited State of Re₂Cl₂(p-OCH₃form)₄

There are only a few reports on the measurement of the energy of the low-lying (3)deltadelta state of quadruply bonded bimetallic complexes, and the direct observation of the (1)deltadelta excited electronic state was only recently reported. In the quadruply bonded bimetallic complexes reported to date, luminescence arises from their (1)deltadelta excited state, and the (3)deltadelta state is nonemissive. Here we report the luminescence of Re(2)Cl(2)(p-OCH(3)form)(4) [p-OCH(3)form = (p-CH(3)OC(6)H(4))NCHN(p-CH(3)OC(6)H(4))(-)] observed upon 400-460 nm excitation with maxima at 820 nm (CH(2)Cl(2), tau = 1.4 micros) and 825 nm (CH(3)CN, tau = 1.3 micros) at 298 K. From the large Stokes shift, the vibronic progression at 77 K, the quenching by O(2), the long lifetime, and the calculated energy of the (3)deltadelta state, the luminescence of Re(2)Cl(2)(p-OCH(3)form)(4) and the corresponding transient absorption signal are assigned as arising from the (3)deltadelta ((3)A(2u)) excited state of the complex.

Crystal structure of tetrakis(μ-n-butyrato-κ²O:O′)bis[chloridorhenium(III)](Re—Re)

et al. 2014

With an inversion center at the mid-point of the two ReIII atoms, the title compound, [Re2Cl2{O2C(CH2)2CH3}4], exhibits a paddle-wheel or lantern-type structure with four n-butyrate groups bridging two ReIII atoms in a syn–syn fashion. The axial chloride ligands together with the Re—Re quadruple bond [2.2330 (3) Å] complete an essentially octahedral geometry around each ReIII atom. There is little distortion, with an Re—Re—Cl bond angle of 176.18 (3)° and typical cis-O—Re—O bond angles ranging from 89.39 (11) to 90.68 (11)°. There are two molecules in the unit cell, and no significant intermolecular interactions were noticed between molecules in the crystal.

“…Complex I is neutral and is composed of dirhenium units with the Re(III) atoms connected by a quadruple bond with the Re-Re distance at 2.2229(3) Å, which is typical for related dirhenium complexes [53][54][55] ( Table 1). The molecule resides on an inversion center, which coincides with the centroid of the Re-Re bond.…”

“…The electronic absorption spectrum (EAS) of I in CH 3 CN exhibits a maximum at ~20,000 cm -1 , which is characteristic of the * transition for the dirhenium tetracarboxylate core [41,54,56 ,57], whereas the maximum at ~25,000 cm -1 corresponds to the electronic transition (Cl)Re 2 for dirhenium tetracarboxylates [54,56,57]. In Figure 2, a shift of the absorption band for Re 2 (RCOO) 4 Cl 2 at 20,000 cm -1 to lower energies and an increase in intensity are observed with A C C E P T E D M A N U S C R I P T…”
