Bis(tetrabutylammonium) tetrachloridomanganate(II) dichloromethane disolvate

IUCrData · 2023-07-14

The title compound, (C 16 H 36 N) 2 [MnCl 4 ]·2CH 2 Cl 2 , is an ionic organic–inorganic hybride compound consisting of a tetrabutylammonium cation and a tetrachloridomanganate(II) anion in a 2:1 stoichiometric ratio. The cation contains a central nitrogen atom bonded to four n -butyl groups in a tetrahedral arrangement, while the anion contains a central Mn II atom tetrahedrally coordinated by four chlorido ligands. It co-crystallized with two equivalents of dichloromethane solvent, CH 2 Cl 2 , to give the following empirical formula: [(C 4 H 9 ) 4 N] 2 [MnCl 4 ]·(CH 2 Cl 2 ) 2 . The crystal structure is mainly stabilized by Coulombic interactions.

Tetraphenylphosphonium tetrakis(trimethylsilanolato)ferrate(III)

IUCrData · 2018-01-09

The structure of tetraphenylphosphonium tetrakis(trimethylsilanolato)ferrate(III), [(C 6 H 5 ) 4 P][Fe(OSi(CH 3 ) 3 ) 4 ], has tetragonal ( I -4) symmetry, and was refined as an inversion twin. It is an ionic compound consisting of a tetraphenylphosphonium cation and a tetrakis(trimethylsilanolato)ferrate(III) anion. The crystal structure comprises the two ionic species each centered on a -4 symmetry element and contributing a fourth of its structure to the asymmetric unit. Each is surrounded by counter-ions on all sides. The cation contains a central phosphorous atom bound to four phenyl groups in a tetrahedral arrangement, while the anion contains a central iron(III) atom tetrahedrally coordinated by four trimethylsilanolato ligands.
