摘要

Tetraphenylarsonium diisothiocyanatodichlorocobaltate(II) was synthesized by metathetic pathway. It crystallizes in the monoclinic space group C 2/c with unit cell parameters, a = 13.510(4) , b = 15.873(5) , c = 22.809(7) , beta = 105.743(6)A degrees, V = 1,618(5) (3) and Z = 4. X-ray crystal structure analysis reveals that the asymmetric unit contains one {(C6H5)(4)As}(+) cation and one half {Co(NCS)(2)Cl-2}(2-) anion, the latter lying on a crystallographic twofold axis. While each {Co(NCS)(2)Cl-2}(2-) anion exhibits hydrogen bonding interactions with eight arsonium cations; CH center dot center dot center dot pi interactions between phenyl rings of arsonium cations is restricted to two such centers in the crystal structure.
