Abstract
The cyclothiazeno complex [Na-15-crown-5][MoF2Cl2(N3S2)] has been prepared by the reaction of sodium fluoride with [MoCl3(N3S2)]2 in acetonitrile solution in the presence of [15-crown-5]. The compound was characterized by its IR spectrum as well as by an X-ray structure determination (3560 observed independent reflexions, R = 0.039). Crystal data: monoclinic, P21/n, Z = 4; a = 1044.8(2); b = 1513.7(2); c = 1363.8(3) pm; β = 104.33(2)°. The structure consists of ion pairs, in which the sodium atom is seven-coordinated by the oxygen atoms of the crown ether molecule and by the two fluorine ligands of the [MoF2Cl2(N3S2)]- unit. The molybdenum atom is a member of the planar MoN3S2 ring; the fluorine atoms are coordinated in trans position to the nitrogen atoms of the cyclothiazeno ring.
