The synthesis and crystallographic characterization of the heterobimetallic dodecanuclear cage cluster: [Et4N](2)[(Mo(2)Ag(2)S(2)O(2)edt(2))(3)(mu(6)-S)]center dot 3H(2)O (edt = -SC2H4S-)

摘要

The crystal structure of the title compound, [Et4N](2)[(Mo(2)Ag(2)S(2)O(2)edt(2))(3)(mu(6)-S). 3H(2)O (edt = SC2H4S-), has been investigated by X-ray diffraction techniques, the crystal is tetragonal, space group P4(1)2(1)2, with a = b = 13.4801(4), c = 37.7381(14) Angstrom, V = 6857.5(4) Angstrom(3) and Z = 4. The anion of the title compound can be viewed as a cage consisting of three [Mo2S2O2(S2C2H4)(2)](2-)/2 Ag+ fragments, with an S2- at the cage center bonding to six Ag atoms. The cage has two big windows each composed of a puckered Ag3S6C6 15-membered ring. [References: 12]
