摘要
The title tetranuclear complex,（μ4-oxo）-hexakis（μ2-chloro）-tetrakis（2-amino-1,3-thiazole-N）-tetra-copper（ii） [Cu4（μ4-O）（μ-Cl）6L4]（1,L=2-amino-1,3-thiazole） was synthesized by the reaction of CuCl2·2H2O with 2-amino-1,3-thiazole in methanol and characterized by IR spectra and X-ray diffraction.Complex 1 crystallizes in triclinic,space group P1 with a=9.7137（2）,b=10.7005（2）,c=14.6505（2）,α=83.9550（10）,β=82.0930（10）,γ=67.1640（10）°,V=1387.84（4）3,Mr=883.43,Z=2,μ=3.927 mm-1,Dc=2.1144 g/cm3,F（000）=868,R=0.0332 and wR=0.0814.The complex contains a tetrahedron of four CuII atoms coordinating to a central μ4-O atom,with the six edges of the tetrahedron bridged by six Cl atoms.The Cu-O bond distances range from 1.910（2） to 1.918（2）,Cu-Cl from 2.3501（11） to 2.5924（10）,and Cu-Cu from 3.1003（6） to 3.1663（6）.The coordination geometries of the four coppers distort from trigonal bipramid to tetragonal pyramid with different distortion factors.The free animo groups of the ligands result in a lot of N-H···Cl and N-H···N intra-and intermolecular hydrogen bonds.
