合成了标题所示的一系列新的含三（取代吡唑）硼氢根的金属配合物，均通过元素分析、ＩＲ、１ＨＮＭＲ进行表征．配合物［η３－ＨＢ（３－（２－ｔｈｉｅ）－５－Ｍｅｐｚ）３］Ｚｎ（ＮＯ３）·１／２ＴＨＦ（２ｃ）的晶体结构测定表明，硝酸根是以不对称双齿方式与Ｚｎ原子配位（Ｚｎ—Ｏ（２）键长为０．１９６６（４）ｎｍ，Ｚｎ—Ｏ（３）键长为０．２４６３（４）ｎｍ）；而在镉的类似物｛［η３－ＨＢ（３－Ｐｈ－５－Ｍｅｐｚ）３］Ｃｄ（ＮＯ３）（ＴＨＦ）｝（２ｅ）中，ＮＯ－３则以双齿方式与Ｃｄ原子配位［Ｃｄ—Ｏ键长为０．２３３４（３）和０．２３５６（３）ｎｍ］．ＮＯ－３随金属不同取不同方式配位的现象，为解释锌、镉碳酸酐酶的不同活性（与酶活性中心配位的ＨＣＯ－３是ＮＯ－３的等电子体）提供了进一步的依据．配合物２ｃ和２ｅ均为三斜晶系，Ｐ１空间群，Ｚ＝２．２ｃ晶胞参数：ａ＝１．１６２５０（１０），ｂ＝１．２４２２（２），ｃ＝１．３２５９０（１０）ｎｍ；α＝７１．４１０（１０）°，β＝７３．０９０（１０）°，γ＝６５．６６０（１０）°；Ｒ＝０．０７５５．２ｅ晶胞参数：ａ＝１．１３０３０（１０），ｂ＝１．２０９９（２），ｃ＝１．２６０７（２?
A series of novel metal complexes containing tris (substituted pyrazoles) borohydride have been synthesized and characterized by elemental analysis, IR and 1HNMR. The crystal structure determination of the complex [η3-HB (3- (2-thie) -5-Mepz) 3] Zn (NO3) · ½THF (2c) shows that the nitrate is formed by asymmetric bidentate coupling with Zn The atomic coordination (Zn-O (2) bond length was 0.1966 (4) nm and Zn-O (3) bond length was 0.2463 (4) nm) (2e), NO-3 coordinated with Cd atom in bidentate manner [Cd-O bond length was 0.2334 (3) And 0.2356 (3) nm]. In order to explain the different activities of zinc and cadmium carbonic anhydrase (HCO-3, which coordinates with the active site of the enzyme, is the NO-3 isomer), NO-3 provides a further basis for coordinating the metal with different ways . The complexes 2c and 2e are triclinic, P1 space group with Z = 2.2c unit cell parameters: a = 1.16250 (10), b = 1.2422 (2), c = 1.32590 ) Nm; α = 71.410 (10) °, β = 73.090 (10) °, γ = 65.660 (10) °; R = 0.0755.2 e unit cell parameters: a = 1.13030 ( 10), b = 1.2099 (2), c = 1.2607 (2?
