چکیده
The asymmetric unit of the title compound, {[Mn3{W(CN)8}2(C16H16N2)3(C3H7NO)3(CH3OH)3]·2H2O} n , consists of three [Mn(N,N-di-methyl-formamide)(methanol)(3,4,7,8-tetra-methyl-1,10-phenanthroline)](2+) cations, two [W(CN)8](3-) anions and two water mol-ecules. Each water mol-ecule is disordered over three sets of sites, with a refined occupancy ratio of 0.310 (9):0.275 (9):0.415 (9) for one mol-ecule and 0.335 (9):0.288 (9):0.377 (9) for the other mol-ecule. The Mn(II) atoms exhibit a distorted octa-hedral geometry, while the W(V) atoms adopt a distorted square-anti-prismatic geometry. The Mn(II) and W(V) atoms are linked alternatively through cyanide groups, forming a tetra-nuclear 12-atom rhombic metallacycle. Adjacent metallacycles are further connected by μ2-bridging cyanide anions, generating a 3,2-chain structure running parallel to [101]. Inter-chain π-π inter-actions are observed [centroid-centroid distances = 3.763 (3) and 3.620 (2) Å].

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) a...
