A novel dimanganese complex linked by an unusually strong hydrogen bond. X-ray structure of the hydrogen-bonded complex and ab initio calculations

In an attempt to prepare the fluoro complex (CO)3(dppe)MnF (3) by treating a CH2Cl2 solution of the aqua complex [(CO)3(dppe)Mn(OH2)]BF4 (1) with NaF(aq), we isolated instead, the dimanganese complex, [(CO)3(dppe)Mn(OH2)FMn(dppe)(CO)3]BF 4 (2). The two moieties, 1 and 3, are held together by an unusually strong O-HF hydrogen bond (OF=2.458(3) ?, HF=1.52 ?) between the aqua ligand on one manganese and the fluoro atom on the other manganese. Using as a simple model the interaction between +Li(H2O) and FLi, the hydrogen bonding distance O-HF was calculated to be; OF=2.443 ?. Authentic 3 was prepared in a homogeneous system using CH2Cl2-soluble [Et4N]F.

The preparation and reactions of the azides of fac-Mn(CO)3(P-P)N3. The X-ray crystal structures of fac-[Mn(CO)3(P-P)(OH2)]BF4, fac-Mn(CO)3(P-P)(NN2C(CF3)N) [(P-P)=dppe and depe], and fac-[Mn(CO)3(depe)(PPh3)]BF4

A simple three-step, high-yield synthesis of the titled azides from Mn2(CO)10 and P-P is described involving the intermediate aqua complexes, fac-[Mn(CO)3(P-P)(H2O)]BF4, 3a,b. The aqua ligand is very labile; it is easily exchanged for D2O, PPh3, and NO2-. Crystal structures of the two titled aqua complexes and fac-[Mn(CO)3(depe)(PPh3)]BF4, 6a, are reported. The aqua complexes react instantaneously with aqueous NaN3 to give quantitative yields of the corresponding covalent azides which undergo the expected 1,3-dipolar additions with CF3CN to give the corresponding tetrazoles whose crystal structures are also reported.
