N2  - Using a sample of 1.06×108ψ(3686) events produced in e+e− collisions at s√=3.686  GeV and collected with the BESIII detector at the BEPCII collider, we present studies of the decays ψ(3686)→K−ΛΞ¯++c.c. and ψ(3686)→γK−ΛΞ¯++c.c.. We observe two hyperons, Ξ(1690)− and Ξ(1820)−, in the K−Λ invariant mass distribution in the decay  (3686)→K−ΛΞ¯++c.c. with significances of 4.9σ and 6.2σ, respectively. The branching fractions of  (3686)→K−ΛΞ¯++c.c., ψ(3686)→K−Σ0Ξ¯++c.c., ψ(3686)→γχcJ→γK−ΛΞ¯++c.c. (J=0, 1, 2), and ψ(3686)→Ξ(1690/1820)−Ξ¯++c.c. with subsequent decay Ξ(1690/1820)−→K−Λ are measured for the first time
