4,4'-[8b,8c-Bis(ethoxycarbonyl)-4,8-dioxo-2,3,5,6-tetra-hydro-1H,4H-2,3a,4a,6,7a,8a-hexa-azacyclo-penta-[def]fluorene-2,6-diyl]dipyridinium bis-(tetra-fluorido-borate).

ABSTRACT: In the title compound, C(26)H(32)N(8)O(6) (2+)·2BF(4) (-), the cation is built up from four fused rings, viz. two nearly planar imidazole rings and two triazine rings exhibiting chair conformations. One eth-oxy group is disordered between two positions in an approximate ratio 3:2. The F atoms of the two anions are each rotationally disordered between two orientations in the same 3:2 ratio. The crystal structure is stabilized by inter-molecular N-H?O, C-H?F and N-H?F inter-actions.

Each six-membered ring has a 2,4-dichloro-benzyl substituent attached to an N atom. In the mol-ecule, the two ethyl groups are each disordered between two orientations in 0.784 (16)/0.216 (16) and 0.631 (10)/0.37 (10) ratios. Weak inter-molecular C-H⋯O hydrogen bonds help to stabilize the crystal packing.

Project description:In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa-hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo-CN-Cu-NC-Mo- linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N-H groups and the water molecules stabilizes this arrangement.
