K(x)H(1-x)Ni(OH2)4[Ru2(CO3)4].zH2O is a ferrimagnet (Tc = 4.3 K) formed from the reaction of K3[Ru(II/III)2(CO3)4] and Ni(II) in water. It possesses a new 3-D network structural motif composed of linked chains and mu3-CO3 linkages to both Ru and Ni sites. Each Ni(II) bonds to four oxygens and to two [Ru2(CO3)4]3- moieties in a cis manner, and four mu3-CO3 groups from each [Ru2(CO3)4](3-) have two oxygens bonding to the Ru2 moiety, forming the typical paddle-wheel core, and trans pairs of the third CO32- oxygen axially bonded to either another Ru2 or Ni(II).
