Abstract
The primary objective of this research is the syntheses of new complexes containing bonds between transition metals and indium. The secondary objective is to synthesize new compounds containing copper, indium and selenium.
A number of transition metal-indium mixed-metal complexes have been synthesized. Their structures have been characterized by single crystal X-ray diffraction as well as other spectroscopic methods. Several compounds containing copper, indium and selenium were also synthesized and characterized.
Fe3(CO)l2 reacted with InCl to give |(CO)4Fe(M- InCl(THF))|2 (1) which further reacted with In-Bu)4NBr producing |(n-Bu)4N]2l(CO)4Fe(|Li-InClBr)j2 (2). Fe(C0)4(THF) is believed to be the intermediate in the preparation of compound (1) in all of the following reactions: Fe3(CO)i2 + InCL Na2Fe(CO)4 + InCl3 and Na2Fe2(CO)8 + InCl3.
The reaction of |{C0)4Fe{ M-lnCI(THF) 1|2 with NaOR (NaOR: sodium 2.4,6-Tri-ieri-hutyl phenoxide) furnished an uncharacterized compound (3) which further reacted with Ph4PBr to yield |PPh4 l2l(CO)4Fe{)Li-lnCIBr) |2 (4). The reaction of Co4(CO)|2 with InBr in THE at room temperature formed | {(CO)4Co } 2lnm-Br) |2 (5) and |(CO)i2Co4lnKBri2i (6). Co4(CO)l2 reacted with InCI to give |((CO)4Co)2ln(|i-CI)|2 (7) and f(CO)i2Co4ln8Cli2l (8). The reaction of compound (5) with PPh3 gave l{(PPh3)Co(CO)3}InBr2(PPh3)] (9) and [ ((PPh3)Co(CO)3 )2ln(|Li Br)J2 (10). Compound (6) reacted with AsPh3 to give |{(AsPh3)Co(CO)3)InBr2(AsPh3)] (11). The reaction of compound (7) with BzEt3NCl produced IBzEt3Nl2l(CO)i2Co4ln8Cli4(CH3CN)4](12).
Ru3(CO)i2 reacted with InCl to yield a cluster which was characterized as |Ru(C0)2ln(THF)|n (where, n > 4) (13) which further reacted with BzEt3NCI to give |Ru(CO)2lnCI(BzEt3N)|n (14).
The reaction of (i-Bu)SeSe(t-Bu) with |(C0D)CuCI)|2 produced |( t-Bu )SeSe(t-Bu )(CuCI )2 In (15). (i-Bu)2Se reacted with |(C0D)CuCI)2 to yield a colorless compound which was characterized as | {(t-Bu)2Se }2CuCI |2 (16).
