以四水合氯化铟（III）为配体，以金刚烷胺和3-/4-甲氧基水杨醛为席夫碱配体，合成了两个配合物：C22 H32 Cl 3 InN 2 O3（1）和C36 H44 Cl 3 InN 2 O 4（2）。通过IR、1H NMR、元素分析、摩尔电导、热分析和单晶X-射线衍射对配合物进行了表征。配合物1属于单斜晶系，P21/n空间群，不对称单元由一个铟（III）、一个N-（3-甲氧基水杨醛）-氨基金刚烷（L1）、三个氯化物和一个N，N-二甲基甲酰胺分子组成。铟通过三个氧和三个氯化物是六配位的，具有倒三角棱柱几何形状。配合物2属于三斜晶系，P1空间群，不对称单元由一个铟（III）、两个N-（4-甲氧基水杨醛）-氨基金刚烷（L2）和三个氯化物组成.铟通过两个氧和三个氯化物形成五配位畸变三角双锥构型。配合物对大肠杆菌和金黄色葡萄球菌的抗菌活性进行了研究。
Indium(III) chloride tetrahydrate and Schiff-base ligands derived from adamantaneamine and 3-/4-methoxysalicylaldehyde gave two complexes, C22H32Cl3InN2O3 (1) and C36H44Cl3InN2O4 (2), respectively. The complexes were characterized by IR, 1H NMR, elemental analysis, molar conductance, thermal analysis, and single-crystal X-ray diffraction. Complex 1 crystallizes in the monoclinic system, P21/n space group with the asymmetric unit consisting of one indium(III), one N-(3-methoxysalicylidene)-aminoadamantane (L1), three chlorides and one N,N-dimethylformamide molecule. The indium is six-coordinate with reversed triangular-prism geometry via three oxygens and three chlorides. Complex 2 crystallizes in the triclinic system, P 1 space group; the asymmetric unit consists of one indium(III), two N-(4methoxysalicylidene)-aminoadamantane (L2), and three chlorides. The indium is five-coordinate with distorted trigonal-bipyramidal geometry via two oxygens and three chlorides. Antibacterial activities of the complexes have been investigated against Escherichia coli and Staphylococcus aureus.
