| Abstract: | Addition of 2 equiv. of PPh3 to MnBr2 in tetrahydrofuran (THF) solution under N2 atmosphere results in the formation of Naldini salt (PPh3)2MnBr2 (1). Reaction of Complex 1 and O2, NO, and CO (with reducing agent) leads to Complex (OPPh3)2MnBr2 (2), (PPh3)2Mn(NO)Br2 (3), and (PPh3)2Mn(CO)3Br (4), respectively. Both Complexes 2 and 4 crystallize in the triclinic space group P‐1 with a = 9.94 Å, b = 10.11 Å, c = 10.53 Å; α = 65.42°, β = 63.16°, and γ = 89.22° of 2 and a = 10.23 Å, b = 12.26 Å, c = 14.44 Å and α = 97.03°, β = 104.34°, and γ = 106.33° of 4. The isoelectronic replacement of 3CO with 2NO yields the {Mn(NO)2}8 species (PPh3)2Mn(NO)2Br (5). The single crystal of 5 is in the monoclinic space group C2/c with a = 23.17 Å, b = 9.62 Å, c = 15.92 Å, and β = 114.91°. In the THF solution, Complex 5 serves as an NO source in the presence of NO trapping, Co(TPP), Co(TPP) = 5,10,15,20‐tetraphenyl‐21H,23H‐porphine cobalt(II). |
