  Three complexes [Cu2(PPh3)4(MeCN)2(cis-(NCN)2sq)]·MeCN 1, [Cu2(dien)2(cis-(NCN)2sq)2]·5H2O}n2 and [Cu(tren)(cis-(NCN)2sq)] 3 where [cis-(NCN)2sq]2− = 3,4-bis(cyanamido)cyclobutane-1,2-dione dianion, have been synthesized and characterized by electronic absorption and IR spectroscopies. The structures of the three complexes have been determined by X-ray crystallography. Complex 1 is present as a dinuclear copper(I) compound. Complex 2 is made of infinite chains with copper(II) atoms bridged by the bis monodentate [cis-(NCN)2sq]2− ion. In the mononuclear complex 3 the co-ordination of the cyanamido group unusually occurs via the amido nitrogen and not by the nitrile group; this is accompanied by an important distortion of the co-ordinated cyanamido group. The co-ordination mode of the cyanamido moiety is discussed in regard to IR data and crystallographic results.

  已经通过电子吸收和红外光谱法合成了并表征了三种复合物：[Cu2(PPh3)4(MeCN)2(cis-(NCN)2sq)]·MeCN 1、[Cu2(dien)2(cis-(NCN)2sq)2]·5H2O}n 2 和 [Cu(tren)(cis-(NCN)2sq)] 3，其中 [cis-(NCN)2sq]2− = 3,4-双(氰胺基)环丁烷-1,2-二酮二阴离子。通过X射线晶体学确定了这三种复合物的结构。复合物1是一种双核铜(I)化合物。复合物2由无限链组成，其中的铜(II)原子被双单齿[cis-(NCN)2sq]2−离子桥接。在单核复合物3中，氰胺基团的配位不寻常地通过氨基氮而不是氰基进行；这伴随着配位的氰胺基团的显著扭曲。结合红外数据和晶体学结果讨论了氰胺基团的配位模式。
