Bis(O-n-butyl dithio-carbonato-κS,S')bis-(pyridine-κN)manganese(II)

Abstract

The structure of the title manganese complex, [Mn(C(5)H(9)OS(2))(2)(C(5)H(5)N)(2)] or [Mn(S(2)CO-n-Bu)(2)(C(5)H(5)N)(2)], consists of discrete monomeric entities with Mn(2+) ions located on centres of inversion. The metal atom is coordinated by a six-coordinate trans-N(2)S(4) donor set with the pyridyl N atoms located in the apical positions. The observed slight deviations from octa-hedral geometry are caused by the bite angle of the bidentate κ(2)-S(2)CO-n-Bu ligands [69.48 (1)°]. The O(CH(2))(3)(CH(3)) chains of the O-n-butyl dithio-carbonate units are disordered over two sets of sites with an occupancy ratio of 0.589 (2):0.411 (2).

Perspective view of the monomeric unit with the atomic numbering scheme. Displacement ellipsoids are drawn at with 50% probability level. The minor disordered alkyl chain is shown for one half of the molecule. Hydrogen atom lables, labels of less than 50% occupied atoms and of symmetry created atoms are omitted for clarity.

Packing plot, view down the b axis (displacement ellipsoids for non-H atoms). Less than 50% occupied atoms are omitted for clarity. Blue dashed lines represent close contacts (less than the sum of the van der Waals radii of the respective atoms) such as C—H···O and S···S contacts.
