Ni II Ru II and Cu II Ru II Coordination Polymers Constructed from [Ru(CN) 6 ] 4−

The dimetallic compounds [Ni(2,3,2‐tet)] 2 [Ru(CN) 6 ]·8H 2 O ( 1 ), [Ni(pn) 2 ] 2 [Ru(CN) 6 ]·5H 2 O ( 2 ) [Ni(tacd)(H 2 O)] 2 [Ru(CN) 6 ]·8H 2 O ( 3 ) and {[Cu(dipn)] 3 [Ru(CN) 6 ]}(ClO 4 ) 2 ·4H 2 O ( 4 ) [2,3,2‐tet = N , N′ ‐bis(2‐aminoethyl)‐1,3‐propanediamine, pn = 1,3‐diaminopropane, tacd = 1,5,9‐triazacyclododecane, dipn = dipropylenetriamine] have been prepared from the reaction of [Ru(CN) 6 ] 4− with [Ni(2,3,2‐tet)] 2+ , [Ni(pn) 2 ] 2+ , [Ni(tacd)(H 2 O)] 2+ and [Cu(dipn)] 2+ , respectively. Compounds 1 and 2 contain a two‐dimensional square network, compound 3 has a one‐dimensional, crossed‐double chain structure, while compound 4 has an unusual, two‐dimensional, double‐edged, honeycomb network. A very weak antiferromagnetic interaction is observed in 2 . (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
