| Abstract: | A dinuclear molybdenum(V) cluster compound (Et4N)2Mo2S4(i-mnt)2] (i-mnt=1,1-dicyanoethylene-2,2-dithiol, S2C=C(CN)2]2-) has been prepared by the ligand substitution reaction of Mo2S4(iso-pr2dtp)2 (iso-pr2dtp=S2P(OC3H7)2?) with K2(i-mnt) in the presence of Et4NI. This cluster was characterized by infrared spectrum, UV-Vis spectrum and single crystal structure analysis. The cluster union Mo2S4(i-mnt)2]2- possesses Cs, symmetry with a crystallographic mirror plane through two bridging S atoms. By the S …? S supramolecular interactions between two adjacent cluster anions the Mo2S4(i-mnt)2]2- anions are linked to form infinite chains along the b axis. Crystal data: monoclinic, space group C2/m, a=1.8748(6), b=1.5380(4), c=1.4322(5) nm, β=112.02(2)°, V=3.823(4) nm3, Z=4, Dc=1.50 g/cm3. The final R=0.038 and Rw=0.053 for 3015 observed unique reflections. |
