“…Following the pioneering work of Kahn's group [13][14][15], these flexible species may be used as versatile synthons to construct a variety of architectures or networks with novel topological structures and interesting magnetic properties. For example, M V -Mn II [16][17][18][19][20][21][22][23][24][25][26], M VMn III , [27,28], and M V -Cu II [29][30][31][32][33][34][35][36][37][38][39][40], bimetallic assemblies with a variety of extended structures, have been obtained; a few polynuclear clusters with M 6 V Mn 9 II type (M = Mo and W) have been reported as well [41][42][43][44][45][46] …”

A cyanide-bridged bimetallic octacyanomolybdate(V)-based polynuclear cluster, {Mn 9 II [Mo V (CN) 8 ] 6 (EtOH) 24 } Á 6EtOH Á 3i-C 3 H 7 OH Á 3H 2 O (1), has been prepared by self-assembling of [Mo(CN) 8 ] 3-and Mn 2? ions. The compound crystallized in the trigonal system with space group R-3 and cell dimensions of a = b = 26.182(15), c = 25.586(14) Å , c = 120°, and Z = 18. The structure of the complex consists of neutral cluster of 15 metal ions, in which all metal ions are linked by cyanide bridged ligands. Magnetic susceptibilities and magnetization measurements of the complex indicate that the cluster has an S = 39/2 ground state. The intracluster ferrimagnetic interaction has been characterized as well.Keywords Cyanide-bridged Á Octacyanomolybdate(V)-based Á Cluster Á Antiferromagnetic interaction Á Ferrimagnet

The aim and the scope of this review is to show the results of ten years of research following the first reports on magnetic and photomagnetic assemblies constructed from. It is illustrated on the basis of our own work as well as a wide range of studies carried out in numerous laboratories around the world. The diversity and evolution of topological and structural patterns is discussed alongside synthetic strategies, which led to the establishment of regular magnetostructural correlations in selected 3D systems. Different types of functionality observed in solid phases are presented with special attention devoted to tuning of magnetic

The reaction between K 3 [Mo(CN) 8 ] Á H 2 O and MnCl 2 Á 4H 2 O in different reaction conditions have obtained three new bimetallic cyanide-bridged compounds, namely, {(tetrenH 2 ) 0.5 [Mn(H 2 O) 2 ][Mo V (CN) 8 ] Á 2H 2 O} n (1) (where, tetren is tetraethylenepentamine), {[Mn 2 (H 2 O) 4 ] [Mo IV (CN) 8 ] Á 3H 2 O} n (2), and {[Mn 2 (H 2 O) 4 ][Mo IV (CN) 8 ] Á 4H 2 O} n (3). Compound 1 crystallizes in the orthorhombic system with space group Cmc21 and unit cell constants a = 7.8234(15), b = 26.013(5), c = 10.021(2) Å , b = 90°, and Z = 4. Compound 2 crystallizes in the monoclinic system with space group P21/n and unit cell constants a = 7.3329(11), b = 14.372(2), c = 18.070(3) Å , b = 90.869(2)°, and Z = 4. Compound 3 crystallizes in the tetragonal system with space group I4/m and unit cell constants a = b = 11.9371(8), c = 13.2930(18) Å , b = 90°, and Z = 4. X-ray single-crystal structures reveal that the Mo centers adopt a distorted square antiprism coordination environment for 1 and 3, while 2 closed to a bicapped trigonal prism. For these complexes, all the Mn II centers in the extended structure adopt distorted octahedron geometry. For 1, each Mo V coordinated via four cyanide groups to four Mn II ions, and the other four cyanide groups are terminal, forming a two-dimensional framework. For 2, the Mo IV center of structural unit coordinated via four cyanide groups to four Mn(1), and the other four cyanide groups coordinated to four Mn(2), forming a three-dimensional framework. For 3, each [Mo IV (CN) 8 ] 4-building block is linked to Mn II ions through its eight CN ligands, and each Mn II center is connected to four Mo units forming a three-dimensional framework. In addition, magnetic studies of these complexes have also been presented.
