An Azide-Bridged Homospin Single-Chain Magnet: [Co(2,2‘-bithiazoline)(N3)2]n

Abstract
A novel end-on azide-bridged homospin 1D chain, Co(bt)(N3)2 (1) (bt = 2,2‘-bithiazoline), is constructed by sharing edges of Co(II) distorted octahedrons to form a helix, which shows magnetic hysteresis with steps and slow relaxation below 5−6 K, typical of single-chain magnet behavior.
