From the reaction of Cd(CH 3 COO) 2 · 2H 2 O with the 1:2 condensate (L) of benzil dihydrazone and 2‐acetylpyridine, [CdL(CH 3 COO)(H 2 O)]PF 6 · 3H 2 O ( 1 ) is isolated by adding NH 4 PF 6 . L reacts with Cd(ClO 4 ) 2 · x H 2 O to yield [CdL 2 ](ClO 4 ) 2 · 0.5H 2 O ( 2 ). The yellowish complexes 1 and 2 are characterized by NMR and single‐crystal X‐ray diffraction. 1 is found to be a seven‐coordinate single helical complex having a Cd II N 4 O 3 core and homoleptic 2 an eight‐coordinate double helical complex with a Cd II N 8 core.(© Wiley‐VCH Verlag GmbH & Co.
