A cyanide-bridged Fe(II)-Nd(III) bimetallic assembly with a one-dimensional ladder-like chain structure.
The title complex, catena-poly[[[(2,2'-bipyridine-1kappa(2)N,N')tris(methanol-2kappaO)(nitrato-2kappa(2)O,O')-mu-cyanido-1:2C:N-cyanido-1kappaC-iron(II)neodymium(III)]-di-mu-cyanido-1:2'C:N;2:1'N:C] methanol solvate], {[Fe(II)Nd(III)(CN)(4)(NO(3))(C(10)H(8)N(2))(CH(3)OH)(3)].CH(3)OH}(n), is made up of ladder-like one-dimensional chains oriented along the c axis. Each ladder consists of two strands based on alternating Fe(II) and Nd(III) centers connected by cyanide bridges. Furthermore, two such parallel chains are connected by additional cyanide cross-pieces (the ;rungs' of the ladder), which likewise connect Fe(II) and Nd(III) centers, such that each [Fe(CN)(4)(bipy)](2-) unit (bipy is 2,2'-bipyridine) coordinates with three Nd(III) centers and each Nd(III) center connects with three different [Fe(CN)(4)(bipy)](2-) units. In the complex, the iron(II) cation is six-coordinated with a distorted octahedral geometry and the neodymium(III) cation is eight-coordinated with a distorted dodecahedral environment.
