Manganese ([Mn(CO)3]) and rhenium tricarbonyl ([Re(CO)3]) complexes represent a workhorse family of compounds with applications in a variety of fields. Here, the coordination, structural, and electrochem. properties of a family of mono- and bimetallic [Mn(CO)3] and [Re(CO)3] complexes are explored. In particular, a novel heterobimetallic complex featuring both [Mn(CO)3] and [Re(CO)3] units supported by 2,2′-bipyrimidine (bpm) has been synthesized, structurally characterized, and compared to the analogous monomeric and homobimetallic complexes. To enable a comprehensive structural anal. for the series of complexes, authors have carried out new single crystal x-ray diffraction studies of seven compounds: Re(CO)3Cl(bpm), anti-[{Re(CO3)Cl}2(bpm)], Mn(CO)3Br(bpz) (bpz = 2,2′-bipyrazine), Mn(CO)3Br(bpm), syn- and anti-[{Mn(CO3)Br}2(bpm)], and syn-[Mn(CO3)Br(bpm)Re(CO)3Br]. Electrochem. studies reveal that the bimetallic complexes are reduced at much more pos. potentials (ΔE ≥ 380 mV) compared to their monometallic analogs. This redox behavior is consistent with introduction of the second tricarbonyl unit which inductively withdraws electron d. from the bridging, redox-active bpm ligand, resulting in more pos. reduction potentials. [Re(CO3)Cl]2(bpm) was reduced with cobaltocene; the ESR spectrum of the product exhibits an isotropic signal (near g = 2) characteristic of a ligand-centered bpm radical. Their findings highlight the facile synthesis as well as the structural characteristics and unique electrochem. behavior of this family of complexes. In addition to this study using Bromopentacarbonylmanganese(I), there are many other studies that have used Bromopentacarbonylmanganese(I)(cas: 14516-54-2SDS of cas: 14516-54-2) was used in this study.
Bromopentacarbonylmanganese(I)(cas: 14516-54-2) has many other uses. It is used in the formation of (eta6-arene)tricarbonylmanganese(I) by reacting with arene (arene= hexamethyl benzene, 1,2,4,5-tetramethyl benzene, mesitylene, p-xylene and toluene) in the presence silver salt.SDS of cas: 14516-54-2
