Synthesis and characterisation of pentacarbonyl(thiazolyl)manganese(0) complexes and their conversion to cationic 2,3-dihydro-thiazol-2-ylidene(pentacarbonyl)manganese(0) compounds: the crystal structures of [(CO)5Mn{}][CF3SO3] and [(CO)5Mn{}][CF3SO3]

Popis:	Treatment of BrMn(CO)5 with the corresponding thiazolyllithium precursor produced [(CO)5Mn{ CNCHCHS }] (1) or [(CO)5Mn{ CN(CH 3 )CHS }] (2). Protonation or alkylation of 1 or 2 yields [(CO)5Mn{ CN(H)CHCHS }][CF3SO3] (3), [(CO)5Mn{ CN(H)C(CH 3 )CHS }][CF3SO3] (4), [(CO)5Mn{ CN(CH 3 )CHCHS }][CF3SO3] (5) or [(CO)5Mn{ CN(CH 3 )C(CH 3 )CHS }][CF3SO3] (6). The relatively long MnC(carbene) bond in the molecular structures of 3 [2.010(12) A] and 4 [2.044(3) A] and structural features of the 2,3-dihydro-thiazol-2-ylidene ligand, attest to stabilisation of the carbene ligand by π-bonding from the N atom and little π-acceptance by the ligand from the metal.
