Abstract

Penelitian sintesis ligan dan kompleks Ni(II) dengan ligan 2-metil-4,5-difenil-1H-imidazol bertujuan untuk mengetahui cara sintesis dan karakterisasi kompleks yang terbentuk. Ligan 2-metil4,5-difenil-1H-imidazol telah disintesis dengan prekursor benzil, ammonium asetat dan asam asetat glasial. Kompleks Ni(II) dengan ligan 2-metil-4,5-difenil-1H-imidazol disintesis dengan perbandingan mol logam dan mol ligan 1:3. Formula kompleks diperkirakan dari analisis kadar Ni dalam kompleks dengan Sepektroskopi Serapan Atom (SSA) adalah [Ni(II)(2-metil-4,5- difenil-1H-imidazol)3(H2O)3]Cl2•6H2O. Analisis dengan metode termogravimerti menunjukkan ada setengah H2O dalam tiap mol kompleks, dengan demikian formula kompleks yang mungkin adalah [Ni(II)(2-metil-4,5-difenil-1Himidazol)3(H2O)3]Cl2•6H2O). Data sepektar FT-IR pada kompleks menunjukkan adanya pergeseran serapan pada gugus O-H, N-H dan Ni-N yang menandakan gugus fungsi tersebut terkoordinasi pada ion pusat Ni2+.Spektra UV-Vis kompleks menghasilkan puncak serapan pada panjang gelombang 324 nm. Hasil Uji toksisitas LC50 sebesar 295,12 ppm menunjukkan bahwa senyawa kompleks tersebut bersifat tidak toksik. ================================================================================================================== The aim of the research is to synthesis and characteristize of ligand and complex of Ni(II) with 2-methyl-4,5-dipenhyl-1Himidazole as ligand. 2-methyl-4,5-diphenyl-1H-imidazole ligand was synthesized using benzile, ammonium acetat and glacial acid. Complex of nikel(II) with 2-methyl-4,5-diphenyl-1H-imidazole have been synthesized 3:1 mole ratio of metal to ligand. The ligand complex formula which by predicted from the result of % nickel in complex using Atomic Absorption Spectroscopy (AAS) and the result of complex formula is [Ni(II)(2-methyl-4,5-diphenyl-1Himidazole)3(H2O)3]Cl2•6H2O. The thermogravimetry indicated that the complex compound has the possible complex is [Ni(II)(2- methyl-4,5-diphenyl-1H-imidazole)3(H2O)3]Cl2•6H2O. The data of the spectroscopy complex compound showed that there is a shift from O-H, N-H and Ni-H functional groups and it became evidence that these functional group formeda coordination bond with Ni2+ . The UV-Vis spectroscopy data showed that there is a transition peak in 324 nm. The LC50 of the complex compound is 295,12 ppm indicated that has not toxicity effect in each mole of complex compound
