摘要: The compound Re$\_2$Cl$\_5$(C$\_4$H$\_{10}$S$\_2$)$\_2$ crystallizes in the monoclinic system with a unit cell of dimensions = 8.023 $\pm$ 0.008 $\overset{\circ}{\mathrm A}$, b 14.355 0.005 c 8.423 0.006 A}, \beta$ 105.5 0.1$^\circ$ occupied by two formula units. space group is P2$\_1$/m. structure, which has been refined to discrepancy index 0.064, consists binuclear units staggered rotational configuration. This result together magnetic data suggests that best formulated as zwitterion, Cl(C$\_4$H$\_{10}$S$\_2$)$\_2$Re$^+$(II) $\equiv$ Re$^-$(III)Cl$\_4$, single unpaired electron occupying singly degenerate orbital localized on rhenium atom formal oxidation state III. metal-metal bond then an order 3. bonding may be compared Re-Re octachlorodirhenium (III) anions and other related structures.
