Abstract

Two novel adducts of formula Mn(hfaC)~2~(NITPhCLI)~2~ (1) and Mn(hfac)2(IMHPhCl)I~2~(NIT‐PhCl) 0.5H~2~O (2), where hfac = hexafluoroacetylacetonate, NITPhCI = 2–(3‐chlorophenyl)‐4,4,5,5‐tetramethylimidazolyl‐1‐oxyl‐3‐oxide, IMHPhCl = 2‐(3‐chlorophenyl)‐4, 4, 5, 5‐tetramethylimidazolyl‐3‐oxide, have been prepared by the reaction of Mn(hfac)~2~ 2H~2~O with NITPhCI. Compound 1 is triclinic, space pup __P‐__1 with a = 1. 3003(3)nm, b= 1.3138(3)nm, c = 1.4931 (3)nm, α = 83.74(3),β= 77.77(3)., σ = 60.59(3)., V = 2.171(1)nm^3^, Z=2. Compound 2 is triclinic, Space group __P‐__1 with a = 1.2994(3) nm, b=1.4841(3) nm, c = 2.1031(4) nm, a = 92.30(3),β= 98.68(3), σ = 97.89(3), V = 3.964(2) nm^3^, Z=2. Each manganese atom is hexacoordinated in both compounds and compound 2 is organized‐ in chains by hydrogen bonds between neighboring pairs of NITPhCI and NITPhCI.
