Herein a library of hybrid Mn‐Anderson polyoxometalates anions are presented: 1 , [(MnMo 6 O 18 )((OCH 2 ) 3 ‐C‐(CH 2 ) 7 CHCH 2 ) 2 ] 3− ; compound 2 , [(MnMo 6 O 18 )((OCH 2 ) 3 C‐NHCH 2 C 16 H 9 ) 2 ] 3− ; compound 3 , [(MnMo 6 O 18 )((OCH 2 ) 3 C‐(CH 2 ) 7 CHCH 2 ) 1 ((OCH 2 ) 3 C‐NHCH 2 C 16 H 9 ) 1 ] 3− ; compound 4 , [(MnMo 6 O 18 )((OCH 2 ) 3 C‐NHC(O)CH 2 CHCH 2 ) 2 ] 3− and compounds 5 – 9 , [(MnMo 6 O 18 )((OCH 2 ) 3 C‐NHC(O)(CH 2 ) x CH 3 ) 2 ]), where x = 4, 10, 12, 14, and 18 respectively. The compounds resulting from the cation exchange of the anions 1 – 9 to give TBA ( a ) and DMDOA ( b ) salts, and additionally for compounds 1 , 2 and 3 , tetraphenylphosphonium (PPh 4 ) ( c ) salts, are explored at the air/water interface using scanning force microscopy, showing a range of architectures including hexagonal structures, nanofibers and other supramolecular forms. Additionally the solid‐state structures for compounds 1c , 2c , 4a , 6a , 9a , are presented for the first time and these investigations demonstrate the delicate interplay between the structure of the covalently derivatised hybrid organo‐clusters as well as the ion‐exchange cation types.
