Tris(acetonitrile-κN){2,6-bis-[(diphenyl-phosphan-yl)amino]-4-eth-oxy-1,3,5-triazine-κP,N,P'}iron(II) bis-(tetra-fluorido-borate) acetonitrile disolvate.

ABSTRACT: In the title compound, [Fe(CH(3)CN)(3)(C(29)H(27)N(5)OP(2))](BF(4))(2)·2CH(3)CN, the Fe(II) ion is octa-hedrally coordinated by a meridionally chelating tridentate pincer-type PNP ligand derived from 2,6-diamino-4-eth-oxy-1,3,5-triazine and by three acetonitrile mol-ecules. The four Fe-N bond lengths range from 1.9142 (12) to 1.9579 (11) Å, while the Fe-P bonds are 2.2452 (4) and 2.2506 (4) Å [P-Fe-P = 165.523 (14)°], consistent with Fe(II) in a low-spin state. Unlike related Fe PNP complexes based on 2,6-diamino-pyridine, the BF(4) anions are not hydrogen bonded to the two NH groups of the pincer ligand but show instead anion-π inter-actions with the triazine ring and acetonitrile mol-ecules in addition to ten C-H⋯F inter-actions. Most remarkable among these is an anion-π(triazine) inter-
