Two types of Ph(3)P/Ph ligated Ag(14)Se(13-x) (x = 0, 0.5) clusters with halite topology were synthesized that differ by the occupation/nonoccupation of the central position by a 13th Se atom and the resulting charge: neutral [(Ph(3)PAg)(8)Ag(6)(mu(6)-Se)(SePh)(12)].11THF (1) and ionic [(Ph(3)PAg)(8)Ag(6)(mu(6)-Se)(0.5)(SePh)(12)][R(3)SnCl(2)].nTHF (R = Ph, n = 6 (2a); Cy, n = 5 (2b)) are all based on a tetradecanuclear cluster. The structural response on the charge was rationalized by DFT calculations, and the optical absorption behavior was studied.
两种具有岩盐拓扑结构的 Ph(3)P/Ph 配位的 Ag(14)Se(13-x)(x = 0,0.5)簇被合成出来,它们的区别在于第 13 个 Se 原子占据/不占据中心位置,以及由此产生的电荷:中性 [(Ph(3)PAg)(8)Ag(6)(mu(6)-Se)(SePh)(12)].11THF(1)和离子 [(Ph(3)PAg)(8)Ag(6)(mu(6)-Se)(0.5)(SePh)(12)][R(3)SnCl(2)].nTHF(R = Ph,n = 6(2a);Cy,n = 5(2b))均基于十四核簇。通过 DFT 计算对电荷的结构响应进行了合理化解释,并研究了其光学吸收行为。
