Use of heterometal combinations to construct very large ring frameworks; synthesis and structural characterisation of the 36-membered ring compound [{NiNd(4-picolylpyrrolidin-2-one)4(NCS)2(NO3)3}n]
Abstract
X-Ray diffraction studies on the complex [{NiNd(PPO)4(NCS)2(NO3)3}n](PPO = 4-picolylpyrrolidin-2-one) show that the PPO ligands connect the Ni and Nd centres into sheets of 36-membered rings; the structure of [CoCl2(PPO)4] is also described.
