Abstract
Abstract A series of complexes of the type trans -[Co(III)(bpb)(amine) 2 ]X (X=NCS, amine=pyrrolidine (prldn) ( 1 ), benzylamine (bzlan) ( 2 ), and X=ClO 4 , amine=pyrrolidine (prldn) ( 3 ), benzylamine (bzlan) ( 4 ), piperidine (pprdn) ( 5 ), morpholine (mrpln) ( 6 ), and bpb= N , N ′-bis(2-pyridinecarboxamide)-1,2-benzene dianion) have been synthesized and characterized by elemental analyses, IR, UV–Vis, and 1 H NMR spectroscopy. The crystal and molecular structure of 1· 0.5H 2 O was determined by X-ray crystallography. The compound crystallizes in the triclinic space group P 1 , a =9.4059(8) A, b =11.3047(10) A, c =12.8451(11) A, α =81.984(2)°, β =83.761(2)°, γ =85.456(2)°, V =1341.6(2) A 3 , Z =2 and final R 1 =0.039 ( wR 2 =0.0625) for 5723 independent reflections with I >2 σ ( I ) and 368 parameters. The structure consists of chains of complexes linked by moderately strong NH⋯OC hydrogen-bonds zig-zagging along the c lattice translation. The IR, UV–Vis, and 1 H NMR spectra of the complexes are also discussed.
