“…The corresponding bond angles are 88.5(1), 91.5(1) and 180 • for the related complex [4]. Akitsu et al reported only one type of hydrogen bonds which is formed between an amine hydrogen atom of 1,2-diphenylethylamine and a carbonyl oxygen atom of the succinimidato ligand for the related complex [4]. The N(2)-H(2N)···O(2) intramolecular hydrogen bond angle was reported as 133 • and the bond length was reported as 2.966(4)Å [4].…”

“…Therefore, the crystal structure determination of the title complex (Scheme 2) was carried out to search for different hydrogen bond interactions. The results are compared with those found in the related complex trans-bis(succinimidato)-bis(1,2-diphenylethylamine) copper(II) [4]. We also studied the IR spectra and the r. t. magnetic susceptibility of the title complex.…”

The molecules of the title compound, [Cu(C 11 H 13 N 2 O 2 ) 2 ], lie across centres of inversion in space group P2 1 /c and are linked by intermolecular N-H···O and C-H···O hydrogen bonds. The central Cu atom has a slightly distorted square-planar coordination comprised of four N atoms. Cu-N bond distances are 1.975(2) and 2.020(2)Å. The interplanar angle between the phenyl and succinimidato ring is 87.34(10) • .

“…1). Additionally, configuration interaction between 3d z2 and 4s orbitals mixing is also subjected to tetrahedral as well as tetragonal distortion of Cu II coordination environment [25][26][27]. However, temperature dependence of (pseudo) Jahn-Teller distortion of Cu II moieties has not been investigated in view of dimensions of cyanide-bridges so far [28][29][30][31].…”

(3), were prepared and characterized structurally. Crystal structures were determined at 263 and 100 K for 1 and 2, while at 299 and 100 K for 3. Thermally-accessible lattice strain resulted in decreasing cell volume of 1.66, 1.06, and 4.1 % for 1-3, respectively. Large thermally-accessible structural change but small pseudo Jahn-Teller elongation at constant temperature could be found in both the long chain of the ladder structure for 3 and the monocuclear Cu II moieties for 1 and 2. In addition, novel mixing of ferromagnetic and antiferromagnetic interactions at low temperature was observed for 3. The correlations between dimensionality of cyanide-bridges and thermally-accessible structural changes distortion associated with Jahn-Teller distortion are also discussed by comparing with several known systems.

Complexes of Ni(II) and Co(II) of the formulae [Ni(H 2 O) 4 (pht) 2 ] (1) and [Co(H 2 O) 4 (pht) 2 ]Á1,5NH 3 ÁH 2 O (2) (where pht = phenotoinate anion) were obtained and characterized physicochemically. [Ni(H 2 O) 4 (pht) 2 ](1) crystallizes in a monoclinic space group P2 1 /c; a = 11.7358(8), b = 11,1250(8), 11.4182(7) Å ; b = 97.076(5)°; V = 1479.41 Å 3 ; Z = 2. The environment around the nickel and cobalt ions can be described as a distorted octahedron. The metal ion was found to bind to four water molecules and two nitrogen atoms derived from two anions of the monodentate phenytoinate. Four intramolecular hydrogen bonds designated as S(6) graph set are found in one [Ni(H 2 O) 4 (pht) 2 ] (1) molecule. Two chain HB patterns, constructed by the [Ni(H 2 O) 4 (pht) 2 ] molecules extending along the c and b axes, respectively, have been observed. The cobalt complex precipitates with the additional solvent molecules: one and a half of ammonia and one water. The results document the preferential binding of hydantoins to the metal ions through N(3) atom.
