Catena-Poly[[bis-(dimethyl-formamide-?O)cadmium]-bis-(?-4-nitro-phenyl-cyanamido-?N:N)].

ABSTRACT: In the title coordination polymer, [Cd(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)(2)](n), the Cd(II) atom, lying on an inversion center, is six-coordinated in a distorted N(4)O(2) octa-hedral geometry. The N atoms of the 4-nitrophenylcyanamide anions form the equatorial plane and the O atoms of the dimethyl-formamide mol-ecules occupy the axial positions. The anions act as bridging ligands, connecting the Cd atoms into a one-dimensional coordination polymer along [100].

catena-Poly[[[bis-(N,N-dimethyl-formamide)iron(II)]-{μ-2,2'-bis-(diphenyl-phosphino-yl)-N,N'-[(1R,2R)-cyclo-hexane-1,2-di-yl]dibenzamide}] bis-(perchlorate) N,N-dimethyl-formamide disolvate].

Project description:The title extended solid coordination compound, {[Fe(C(44)H(40)N(2)O(4)P(2))(C(3)H(7)NO)(2)](ClO(4))(2)·2C(3)H(7)NO}(n), was crystallized un-ex-pectedly from the reaction mixture containing the Trost ligand (1R,2R)-(+)-1,2-diamino-cyclo-hexane-N,N'-bis-(2'-di-phenyl-phosphinobenzo-yl) and Fe(ClO(4))(2)·6H(2)O in a 1:1 ratio in dimethyl-formamide (DMF) under reflux conditions. The polymeric complex is characterized by Fe(II) metal centers that are coordinated by two oxidized Trost ligands, each coordinated in a bidentate fashion in a square plane, along with two DMF mol-ecules above and below the plane [average Fe-O(DMF) = 2.086 (4) Å], forming an overall pseudo-octa-hedral geometry. The Trost ligand binds adjacent Fe(II) centers, each Fe(II) being bound through the O atom of one of the phosphine oxides [average Fe-O(PPh2) = 2.115 (4) Å] and the carbonyl O atom of the adjacent amide [average Fe-O(amide) = 2.192 (3) Å]. Disorder is observed in the co-solvated solvent: there are two DMF mol-ecules per Fe(II) centre, which were modeled as one DMF mol-ecule with complete occupancy and the other being modeled in two positions with equal occupancy. Disorder was also observed with one of the perchlorate anions, which was modeled in two positions with 0.75:0.25 occupancy.
