Synthesis and crystal structure of silver (I) perchlorate π-complexe with 5-(2,4-dichloro-phenyl)-N-allyl-1,3,4-thiadiazol-2-amine of [Ag2(C11H9Cl2N3S)2(ClO4)2] composition

Abstract

In the structure, perchlorate anion, silver atoms as well as allyl group carbon atoms are disordered. 2,4-Dichlorophenyl ring is also disordered due to rotating of the phenyl ring relative to 1,3,4-thiadiazole core. The Ag1A-O1 i distance of 3,165(8) Å (i =1-x, 1-y, 1-z) is significantly longer than the Ag1A-O1 one of 2,788(8) Å, but still shorter than the sum of van-der-Vaals radii of silver and oxygen. The metal site disordering causes an appearance of Ag1B-O1 i bond of 2,853(8) Å, which is closer to the Ag1A-O1 bond length.
