Abstract

A series of copper and zinc pentafluorobenzoate (pfb) and trifluoroacetate compounds with phosphorus-containing pyrrolidine derivatives are synthesized: [Cu(L1–F)2(CF3COO)2] (1, L1–F - (3-(3-fluorobenzylidene)pyrrolidin-2-yl-)di(p-hexyl)phosphinoxide), [Cu(L2–Cl)2(CF3COO)2] (2, L2–Cl - (3-(4-chlorobenzylidene)pyrrolidin-2-yl-)di(p-hexyl)phosphinoxide), [Cu(L2–Br)2(CF3COO)2] (3, L2–Br - (3-(4-bromobenzylidene)pyrrolidin-2-yl-)di(p-hexyl)phosphinoxide), [Zn2(L2–Cl)2(CF3COO)4] (4), [Zn2(L3–Et)2(C6F5COO)4] (5, L3–Et - (1-(ethylsulfonide)pyrrolidin-2-yl)diphenylphosphinoxide), [Cu2(L3–Et)2(C6F5COO)4]·2MeCN (6), [Cu2(L3–Vi)2(C6F5COO)4] (7, L3–Vi - (1-(vinylsulfonyl)pyrrolidin-2-yl)diphenylphosphinoxide). The coordination compounds obtained are characterized by single crystal X-ray diffraction, IR spectroscopy, and the CHNS analysis. The structures and crystal packings of the obtained complexes are studied in detail and the main structure-forming non-covalent interactions are revealed in the crystals.
