摘要：

The crystal structures of several dinuclear complexes of manganese are reported, and the decomposition and analysis of the nanostructured products derived from them are presented. 1,4,7,10-Tetraazacyclododecane (cyclen) forms dinuclear complexes 1-4 containing doubly oxo-bridged or oxo-acetato bridging ligands depending on the manganese salt used for the reaction. Doubly oxo-bridged 1 crystallizes in the orthorhombic space group Pnma, a = 22.3850(14) angstrom, b = 9.1934(5) angstrom, c = 13.2424(10) angstrom, V = 2725.2(3) angstrom(3). 2, containing [Mn(SCN)(5)](3-) conteranions, crystallizes in monoclinic space group l2/a with a = 18.2699(10) angstrom, b = 11.2384(6) angstrom, c = 18.6432(g) angstrom, alpha = 90.00 degrees, beta = 14.510(6)degrees, gamma = 90.00 degrees, V = 3483.0(3) angstrom(3). Oxo-acetato-bridged 3 crystallizes in orthorhombic space group Pca21, a = 13.9322(11) angstrom, b = 16.2332(13) angstrom, c = 14.6794(8) angstrom, V 3320.0(4) angstrom 3. Compound 4 consists of a templated quasi-one-dimensional manganese oxalate crystallized in the triclinic space group P1, a = 9.5442(11) angstrom, b = 10.3758(10) angstrom, c = 21.851(2) angstrom, alpha = 83.720(12)degrees, beta = 80.106(13)degrees, gamma = 85.457(13)degrees, V = 2114.9(4) angstrom(3). Compounds 1, 3, and 4 decompose to nanostructured oxide materials, which may be isolated in bulk as lamellar-structured particles or microspheres or deposited on substrates.
