Cobalt(II) chloride complex with Bi-1,1′-(3,3-dimethyl-3,4-dihydroisoquinoline): Synthesis, crystal structure, and spectra
摘要:
The complex of cobalt(II) chloride with bi-1,1'-(3,3-dimethyl-3,4-dihydroisoquinoline) (L), [CoLCl(2)] (I), is synthesized and studied by X-ray diffraction, electronic spectroscopy, and IR spectroscopy. In the structure of complex I, ligand L performs a bidentate-chelating function, adding to the cobalt atom through the nitrogen atoms. The coordination polyhedron of the cobalt atom is a tetrahedron (2N, 2Cl) with ordinary Co-N (2.00(1)-2.07(1) angstrom) and Co-Cl (2.216(6)-2.226(6) angstrom) bond lengths. The noncentrosymmetric orthorhombic unit cell of crystal I contains two independent molecules of the complex (1 and 1') joined by C-H=Cl hydrogen bonds into a pseudocentrosymmetric dimer. Ligands L(c) and L'(c) exist in the same cisoid isomeric form (torsion angle N(1)-C(1)-C(12)-N(2) is 19.2 degrees in L(c) and 26.6 degrees in L'(c)).

The copper chloride complex with bis-1,1'-(3,3-dimethyl-3,4-dihydroisoquinoline) (L) was synthesized and characterized by X-ray diffraction and UV/Vis and IR spectroscopy. The structure of the complex [Cu2L2Cl4] is built of centrosymmetric binuclear molecules with a double chlorine bridge. The coordination five-vertex polyhedron of copper is a heavily distorted tetragonal pyramid with a considerably nonplanar base in which the vertices are occupied by chlorine atoms (bridging Cl(1) and Cl(1A) and terminal Cl(2)) and the nitrogen atom N(2); the axial vertex is occupied by N(1). The bond lengths, Cu-N-eq (2.013(1) angstrom), Cu-N-ax (2.392(2) angstrom), Cu-Cl-bridge (2.305(1) and 2.342(1)), and Cu-N-term (2.251(1) angstrom), are markedly different. The coordinated ligand occurs in the cisoid form (the N(1)C(1)C(12)N(2) torsion angle is -32.6 degrees).
