Abstract: The copper(I) complex of L, the 1:2 condensate of benzil dihydrazone and 2-formylpyridine, exists as single helical [CuL]+ and double helical [Cu2L2]+ in dichloromethane solution but crystallizes only as the double helicate [Cu2L2](ClO4)2.In contrast, earlier [New J Chem, 27 (2003) 193) it has been round that with L', the 1:2 condensate of benzil dihydrazone and 2-acetylpyridine, only the single helical monomeric species [CuLʹ]+ is isolable as solid. This contrasting behaviour of the copper(I) complexes of Land Lʹ are scrutinised here by density functional calculations.
