Manganese clusters derived from 2-pyridylcyanoxime: new topologies and a large spin ground state in pyridyloximate chemistry†‡
Abstract
Series of manganese clusters derived from 2-pyridylcyanoxime with Mn3II (1), Mn4II (2a, b), MnII4MnIII4 (3), MnII2MnIII6MnIV2 (4) and MnII3MnIII6MnIV (5) cores have been characterized. Dc magnetic measurements reveal antiferromagnetic coupling for 1–4 and dominant ferromagnetic interactions for 5 which shows the largest ground state reported to date in pyridyloximate chemistry (S = 14).
