ABSTRACT: The title complex, {[Fe(II)Y(III)(CN)(4)(NO(3))(C(10)H(8)N(2))(CH(3)OH)(3)]·CH(3)OH·0.5H(2)O}(n), is built up of ladder-like chains oriented along the c axis. Each ladder consists of two strands based on alternating Fe(II) and Y(III) ions connected by cyanide bridges. Two such parallel chains are connected by additional cyanide anions (the 'rungs' of the ladder), which likewise connect Fe(II) and Y(III) ions, such that each [Fe(bipy)(CN)(4)](2-) (bipy is 2,2'-bipyridine) unit coordinates with three Y(III) ions and each Y(III) ion connects with three different [Fe(bipy)(CN)(4)](2-) units. The Fe(II) atom is six-coordinated in a distorted octa-hedral geometry and the Y(III) atom cation is eight-coordinated in a distorted dodeca-hedral environment. The uncoordinated methanol solvent mol-ecule
