Abstract
AbstractA wheel‐like dodecanuclear cobalt(II) cluster complex [Co12(TBSOC)4(5‐NH2‐tz)8(CH3OH)6]·3H2O·5CH3OH (1, 5‐NH2‐tzH = 5‐amino‐1H‐tetrazole) and an irregular rod‐like tetradecanuclear cobalt(II) cluster complex [Co14(OH)2(TBSOC)4(5‐ph‐tz)10(5‐ph‐tzH)2(CH3OH)2]·16·5H2O·2CH3OH(2, 5‐ph‐tzH = 5‐phenyl‐1H‐tetrazole) were solvothermally synthesized by using p‐tert‐butylsulfonylcalix[4]arene (H4TBSOC) and 5‐subst‐1H‐tetrazoles as ligands. Single‐crystal X‐ray diffraction analyses revealed that the 5‐substituent groups of the 1H‐tetrazole bridging ligands have asignificant influence on the structure of the polynuclear cobalt(II) cluster complexes: 1 shows a closed wheel‐like structure whereas 2 an open rod‐like structure. A magnetic investigation indicated that both complexes exhibit antiferromagnetic properties.
