Abstract
Senyawa kompleks Co(II) dengan ligan 2(4-nitrofenil)-
4,5-difenil- 1H- imidazol telah berhasil disintesis. Kompleks yang
didapatkan berwujud kristal jarum berwarna kuning dengan
rumus molekul [Co(2(4-nitrofenil)- 4,5-difenil- 1H- imidazol)3].
Rumus molekul kompleks didukung oleh hasil analisis elemental
analyzer (C= 70,305%, H= 4,535% dan N= 11,559%), analisis
SSA (Co= 5,53%), dan spektrum FTIR yang menunjukkan
adanya puncak khas Co-N dan Co-O pada bilangan gelombang
408,88 cm-1 dan 543 cm-1. Uji toksisitas dengan metode Brine
Shrimp Lethality Test (BSLT) dari kompleks Co(II)- 2(4-
nitrofenil)- 4,5-difenil- 1H- imidazol menunjukkan nilai LC50
sebesar 265,79 mg/L yang mengindikasikan bahwa kompleks
tersebut tidak toksik.

Complex compounds Co(II) with the ligand 2(4-
nitrophenyl) -4,5-diphenyl- 1H- imidazole has been successfully
synthesized. The complex obtained tangible yellow needle
crystals with molecular formula [Co(2(4-nitrophenyl)- 4,5-
diphenyl- 1H- imidazole) 3]. Complex molecular formula is
supported by the results of the analysis of elemental analyzer (C =
70.305%, H = 4.535% and N = 11.559%), SSA analysis (Co =
5,53%), and the FTIR spectrum showed the typical peaks Co-N
and Co-O on 408.88 wave numbers cm-1 and 543 cm-1. Toxicity
test method Brine Shrimp Lethality Test (BSLT) of the complex
Co(II)-2 (4-nitrophenyl)- 4,5-diphenyl- 1H- imidazole showed
LC50 values of 265.79 mg/L indicating that the compound is not
toxic.
