Structures are reported for six closely related salts of tris-(bipyrid-yl)iron(II) cations, namely tris-(2,2'-bi-pyridine)-iron(II) bis-(1,1,3,3-tetra-cyano-2-meth-oxy-propenide) 0.776-hydrate, [Fe(C 10 H 8 N 2 ) 3 ](C 8 H 3 N 4 O) 2 .0.776H 2 O, (I), tris-(2,2'-bi-pyridine)-iron(II) 1,1,3,3-tetra-cyano-2-(propyl-sulfan-yl)propenide perchlor-ate, [Fe(C 10 H 8 N 2 ) 3 ](C 10 H 7 N 4 S)(ClO 4 ), (II), tris-(5,5'-dimethyl-2,2'-bi-pyridine)-iron(II) 1,1,3,3-tetra-cyano-2-meth-oxy-propenide tetra-fluorido-borate ethanol 0.926-solvate, [Fe(C 12 H 12 N 2 ) 3 ](C 8 H 3 N 4 O)(BF 4 ).0.926C 2 H 2 O, (III), tris-(5,5'-dimethyl-2,2'-bi-pyridine)-iron(II) 1,1,3,3-tetra-cyano-2-eth-oxy-propenide tetra-fluorido-borate, [Fe(C 12 H 12 N 2 ) 3 ](C 9 H 5 N 4 O)(BF 4 ), (IV), tris-(5,5'-dimethyl-2,2'-bi-pyridine)-iron(II) 1,1,3,3-tetra-cyano-2-(ethyl-sufanyl)propenide tetra-fluorido-borate, [Fe(C 12 H 12 N 2 ) 3 ](C 9 H 5 N 4 S)(BF 4 ), (V), and tris-(5,5'-dimethyl-2,2'-bi-pyri-dine)-iron(II) 1,1,3,3-tetra-cyano-2-prop-oxypropenide tetra-fluorido-borate, [Fe(C 12 H 12 N 2 ) 3 ](C 10 H 7 N 4 O)(BF 4 ), (VI). In compound (I), one of the anions is disordered over two sets of atomic sites with equal occupancies while, in the second anion, just one of the C(CN) 2 units is disordered, again over two sets of atomic sites with equal occupancies: the anionic components are linked by multiple C-H⋯N hydrogen bonds to form a three-dimensional framework. In compound (II), the polynitrile anion is disordered over two sets of atomic sites with occupancies in the approximate ratio 3:1, while the perchlorate anion is disordered over three sets of atomic sites: there are C-N⋯π inter-actions between the cations and the polynitrile anion. The polynitrile anion in compound (III) is fully ordered, but the tetra-fluorido-borate anion is disordered over two sets of atomic sites with occupancies 0.671 (4) and 0.329 (4): the cations and the tetra-fluorido-borate anions are linked by C-H⋯F inter-actions to form an inter-rupted chain. Compounds (IV) and (V) are isostructural and all of the ionic components are fully ordered in both of them: the cations and tetra-fluorido-borate anions are linked into C 2 2 (12) chains. The polynitrile anion in compound (VI) is disordered over two sets of atomic sites with approximately equal occupancies, and here the chains formed by the cations and the tetra-fluorido-borate anions are of the C 2 2 (13) type. |
