The title complex, Ca(C(27)H(30)N(4)O(3))(2)(2)·2CH(3)CN, is composed of centrosymmetric (CaL(2))(2+) cations [L = tris-(2-hy-droxy-benzoyl-amino-eth-yl)amine = H(3)saltren], uncoordin-ated perchlorate anions and acetonitrile solvent mol-ecules. The calcium ion is six-coordinated and is bonded to all phen-oxy O atoms from both zwitterionic saltren mol-ecules. There are strong intra-molecular N-H⋯O hydrogen bonds. The cations are linked into chains via weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π and π-π stacking inter-actions [centroid-centroid distances = 3.306 (3) and 3.415 (3) Å].
标题配合物Ca(C₂₇H₃₀N₄O₃)₂₂·2CH₃CN由中心对称的(CaL₂)²⁺阳离子[L = 三(2 - 羟基苯甲酰氨基乙基)胺 = H₃saltren]、未配位的高氯酸根阴离子和乙腈溶剂分子组成。钙离子为六配位，与两个两性离子saltren分子中的所有苯氧基O原子键合。存在强的分子内N - H⋯O氢键。阳离子通过弱的分子间C - H⋯O氢键以及C - H⋯π和π - π堆积相互作用[质心 - 质心距离 = 3.306(3)和3.415(3) Å]连接成链。
