The crystal structures of three first-row transition metal-pyridine-sulfate complexes, namely catena-poly[[tetrakis(pyridine-κN)nickel(II)]-μ-sulfato-κO:O'], [Ni(SO)(CHN)], (1), di-μ-sulfato-κO:O-bis[tris(pyridine-κN)copper(II)], [Cu(SO)(CHN)], (2), and catena-poly[[tetrakis(pyridine-κN)zinc(II)]-μ-sulfato-κO:O'-[bis(pyridine-κN)zinc(II)]-μ-sulfato-κO:O'], [Zn(SO)(CHN)], (3), are reported. Ni compound (1) displays a polymeric crystal structure, with infinite chains of Ni atoms adopting an octahedral NO coordination environment that involves four pyridine ligands and two bridging sulfate ligands. Cu compound (2) features a dimeric molecular structure, with the Cu atoms possessing square-pyramidal NO coordination environments that contain three pyridine ligands and two bridging sulfate ligands. Zn compound (3) exhibits a polymeric crystal structure of infinite chains, with two alternating zinc coordination environments, i.e. octahedral NO coordination involving four pyridine ligands and two bridging sulfate ligands, and tetrahedral NO coordination containing two pyridine ligands and two bridging sulfate ligands. The observed coordination environments are consistent with those predicted by crystal field theory.
报道了三种第一排过渡金属 - 吡啶 - 硫酸盐配合物的晶体结构，即链状聚[[四（吡啶 - κN）镍（II）]-μ-硫酸根 - κO:O']，[Ni(SO)(CHN)]，（1）；二 - μ-硫酸根 - κO:O - 双[三（吡啶 - κN）铜（II）]，[Cu(SO)(CHN)]，（2）；以及链状聚[[四（吡啶 - κN）锌（II）]-μ-硫酸根 - κO:O'-[双（吡啶 - κN）锌（II）]-μ-硫酸根 - κO:O']，[Zn(SO)(CHN)]，（3）。镍化合物（1）呈现出聚合物晶体结构，镍原子的无限链采用八面体NO配位环境，涉及四个吡啶配体和两个桥连硫酸根配体。铜化合物（2）具有二聚体分子结构，铜原子具有四方锥NO配位环境，包含三个吡啶配体和两个桥连硫酸根配体。锌化合物（3）表现出无限链的聚合物晶体结构，具有两种交替的锌配位环境，即涉及四个吡啶配体和两个桥连硫酸根配体的八面体NO配位，以及包含两个吡啶配体和两个桥连硫酸根配体的四面体NO配位。观察到的配位环境与晶体场理论预测的一致。
