Crystal structure of a second polymorph of tricarbon­yl(N-methyl­pyridine-2-carboxamide-κ2N1,O)(thio­cyanato-κN)rhenium(I)

A new polymorph of the title compound, [Re(NCS)(C7H8N2O)(CO)3], crystallizing in the space group P21/n, has been obtained and structurally characterized by the experiment and DFT calculations. In this complex, the rhenium(I) cation is octa­hedrally coordinated by three carbonyl groups in a facial configuration, the N,O-bidentate N-methyl­pyridine-2-carboxamide ligand and the N-bonded thio­cyanate anion. Neighbouring mol­ecules are linked into a three-dimensional network by inter­molecular N—H⋯S and C—H⋯S inter­actions.
