Abstract
The title compound is monoclinic,M r =337.8,P21/c-C 52h (No. 14),a=5.508(2),b=13.944(6),c=18.238(5) Å,β=95.99(3)°,V=1393.1(9) Å3,Z=4,D x =1.61 g cm−3, λ(MoKα)=0.71073 Å,F(000)=660.0,μ=10.3 cm−1, finalR=0.051 for 2122 observed [I>3σ(I)] reflections. The two six-membered rings resulting from the coordination of the 1,3-propanediamine ligands to the chromium atom are in the chair conformation. The Cr-N and Cr-F distances average 2.085(4) and 1.876(3) Å, respectively.
