Synthesis, structure and dielectric constant property of two novel complexes based on protonated 1-aminoadamantane

The odd–even effect in n-carboxyalkylammonium-containing organic–inorganic hybrids of Mn(ii) halides: structural and magnetic characterisation

“…A search of the CSD (Version 5.43, June 2022 update) 39 showed that only two structures containing only one type of organic cation and a [MnCl 4 (H 2 O) 2 ] 2− anion have been reported in the literature. These structures are EHIWIC , 54 which contains an adamantanylammonium cation and TAKZOV , 55 that contains a carbamolguanidinium cation. In both literature structures the [MnCl 4 (H 2 O) 2 ] 2− anion adopts a trans conformation, and the same 1D hydrogen bonded ribbon that is observed in structures C3MnClH 2 O and C5MnClH 2 O , is formed between the anions.…”
