摘　　要：制备了五配位单核钴配合物[Co(TMC)Cl]ClO_4(1,TMC=1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane)。配合物1结晶于单斜晶系:P21,晶胞参数为a=0.805 95(7) nm,b=1.486 58(12) nm,c=0.813 64(7) nm,β=110.190(2)°,V=0.914 93(13) nm^3,Z=2,T=120(2) K。钴与来自TMC配体的4个氮原子和1个氯离子配位,形成了扭曲的四方锥配位构型。磁性测试揭示了高自旋的钴离子具有场诱导的慢弛豫行为。A pentacoordinate mononuclear cobalt(Ⅱ) complex,[Co(TMC)Cl]ClO4 (1, TMC=1,4,7,10-tetramethyl-1, 4,7,10-tetraazacyclododecane), is synthesized. It crystallizes in the monoclinic P21 with a=0.805 95(7) nm, b=1.486 58(12) nm, c=0.813 64(7) nm,β=110.190(2)°, V=0.914 93(13) nm^3, Z=2, T=120(2) K. The Co(Ⅱ) ion is coordinated to four N atoms from the TMC ligand and one Cl- ion. The geometry of cobalt atom is best described as a distorted square pyramid. The magnetic measurements reveal the field induced slow relaxation behavior for the high-spin Co(Ⅱ) ion. CCDC: 1849513.
