标题化合物[Fe(C9 H10 BN 6)2]是先前报道的化合物[奥利弗等人(1980)]的多晶型物。Inorg.Chem.19,165-168]。在先前的报告中,该化合物在单斜晶系空间群P21/c(Z = 4)中结晶,而本文报道的化合物的晶体对称性为四斜晶系(P42/ncm,Z = 4)。分子结构由两个氢化三(1-吡唑基)硼酸盐配体(Tp−)和一个中心FeII离子组成,该离子与两个Tp−配体的六个吡唑N原子配位,产生扭曲的双锥FeN 6几何结构。完整的分子具有对称性2/m。
The title compound, [Fe(C9H10BN6)2], is a polymorph of a compound reported previously [Oliver et al. (1980). Inorg. Chem. 19, 165–168]. In the previous report, the compound crystallized in the monoclinic space group P21/c (Z = 4), whereas the crystal symmetry of the compound reported here is tetragonal (P42/ncm, Z = 4). The molecular structure is comprised of two hydrotris(1-pyrazolyl)borate ligands (Tp−) and a central FeII ion, which is coordinated by six pyrazole N atoms from two two Tp− ligands, yielding a distorted bipyramidal FeN6 geometry. The complete molecule exhibits symmetry 2/m.
