1-D polymer containing the [Ru-N-Ru] mu-nitrido moiety: crystal structure and magnetic properties of ([Cu(en)2]3[Ru2N(CN)10].ClO4)n (en = 1,2-diaminoethane).
A novel (mu-nitrido-diruthenium)-bridged 1-D coordination polymer was formed from reaction of K5[Ru2N(CN)10] with [Cu(en)2](ClO4)2; a similar reaction with [Cu(pn)2][(ClO4)2] (pn = 1,3-diaminopropane) gave ([Cu(pn)2]5[Ru2N(CN)10]2) as a discrete molecular compound; variable temperature susceptibility measurements show that there is a weak ferromagnetic interaction between the Cu(II) ions in 1-D polymer.
