Abstract

A novel ligated reagent complex is provided. The ligated reagent includes at least one zero-valent atom, whether metal, metalloid, or non-metal, in complex with at least one hydride molecule and at least one nitrile compound. The ligated reagent complex can be useful in the synthesis of nanoparticles. Also provided is a method for preparing a ligated reagent complex. The method includes a step of ball-milling a mixture that includes a preparation containing a zero-valent element, a hydride molecule, and a nitrile compound.

First claim

What is claimed is:

1. A composition comprising a complex according to a formula,
Q 0 ·X y ·L z ,

wherein Q 0 is a zero-valent element, X is a hydride, y is an integral or fractional value greater than zero, L is a nitrile, and z is an integral or fractional value greater than zero; and
wherein the hydride can be any of a binary metal hydride, a binary metalloid hydride, a complex metal hydride, and a complex metalloid hydride.

2. The composition as recited in claim 1 , wherein Q 0 is a transition metal.

3. The composition as recited in claim 1 , wherein Q 0 is manganese.

4. The composition as recited in claim 1 , wherein X is lithium borohydride.

5. The composition as recited in claim 1 , wherein L is dodecane nitrile.

6. The composition as recited in claim 1 , wherein each of y and z is about 4 or less.

7. A method for synthesizing a reagent complex, comprising:
ball-milling a mixture containing a preparation containing a zero-valent metal, a hydride and a nitrile.

8. The method as recited in claim 7 , wherein the hydride is a complex metal hydride or a complex metalloid hydride.

9. The method as recited in claim 7 , wherein the hydride is lithium borohydride.

10. The method as recited in claim 7 , wherein the hydride and the preparation containing a zero-valent metal are mixed in substantially equimolar proportion.

11. The method as recited in claim 7 , wherein the hydride is mixed with the preparation containing a zero-valent metal in about four-fold or lower molar excess.

12. The method as recited in claim 7 , wherein the ball-milling is performed in an oxygen-free environment, in an anhydrous environment, or in an environment that is oxygen-free and anhydrous.

13. The method as recited in claim 7 , wherein the preparation containing a zero-valent metal is a preparation containing a transition metal.

14. The method as recited in claim 7 , wherein the preparation containing a zero-valent metal is a preparation containing manganese.

15. A ligated reagent complex prepared by a method comprising:
ball-milling a mixture of a hydride with a preparation containing a zero-valent metal.

16. The ligated reagent complex as recited in claim 15 , wherein the hydride is a complex metal hydride or a complex metalloid hydride.

17. The ligated reagent complex as recited in claim 15 , wherein the hydride is lithium borohydride.

18. The ligated reagent complex as recited in claim 15 , wherein the ball-milling is performed in an oxygen-free environment, in an anhydrous environment, or in an environment that is oxygen-free and anhydrous.

19. The ligated reagent complex as recited in claim 15 , wherein the preparation containing a zero-valent metal is a preparation containing a transition-metal.

20. The ligated reagent complex as recited in claim 15 , wherein the preparation containing a zero-valent metal is a preparation containing manganese.
