Structure and preliminary electron distribution of copper heptanoate from room-temperature X-ray data

Abstract

Tetrakis(μ-heptanoato-κO:κO')dicopper [Cu 2 (C 7 H 13 O 2 ) 4 ], M r =643.4, triclinic, P1, a=5.170 (1), b=8.518, c=19.217 (2) A, α=86.65 (1), β=83.60 (1), γ=75.46 (1) o , V=813.78 A 3 . The unit cell contains one dicopper dimer (Z=1), D x =1.314 g cm -3 , μ=1.350 mm -1 for Mo Kα radiation (λ=0.70928 A), R(F)=0.038 for 4861 reflections. The copper-copper distance in the dimer is 2.578 A and each copper is surrounded by five O atoms and one Cu atom in a pseudo-octahedral coordination polyhedron. The copper-copper distance between two dimers is 3.232 A
