Dl. Bond et al., A new structural class of lanthanide carbonates: Synthesis, properties, and X-ray structure of the one-dimensional ch sin complex [Co(NH3)(6)](6)[K-2(H2O)(10)]-[Nd-2(CO3)(8)](2)center dot 20H(2)O, INORG CHEM, 39(17), 2000, pp. 3934
The neodymium tetracarbonate complex [Co(NH3)(6)](6)-[K-2(H2O)(10)][Nd-2(CO
3)(8)](2). 20H(2)O (1) has bt:en prepared and characterized. A single-cryst
al X-ray diffraction study of 1 reveals a pseudo-one-dimensional infinite c
hain of nine-coordinate neodymium metal centers, each complexed by three bi
dentate carbonate ligands in a pseudoequatorial fashion, while a fourth bid
entate carbonate group occupies an axial coordination site on each metal an
d acts as a mu(2)-eta(2),eta(1) bridge between adjacent chain units.
