“…If we use the structure parameters of crystals B and C (Table 3) [17] in addi tion to the structural information obtained in the present study, the C o-C 2 and C o -C 3 distances can be estimated as 482-490 and 534-539 pm, respec tively, in good agreement with the experimental peak positions (Table 2).…”

“…The two peaks in the region of 450 to 550 pm in DCo(r) are presumed to be attributed to the methyl carbon atoms (C2 and C3) of the coordinated DMF molecule, since their peak positions are close to those expected from the planar structure of DMF in the crystalline solvates [17]. If we use the structure parameters of crystals B and C (Table 3) [17] in addi tion to the structural information obtained in the present study, the C o-C 2 and C o -C 3 distances can be estimated as 482-490 and 534-539 pm, respec tively, in good agreement with the experimental peak positions (Table 2).…”

“…This indicates that the nitrogen atom is situated trans to the metal atom in the O -C j-N plane. Assuming this geometry, we can estimate the C o-N distance as 425 to 429 pm, close to the experimental one by use of the structure parameters of a DMF molecule (Table 3) [14,[17][18][19] as well as the C o-O and Co-C! distances ( Table 2).…”

“…The Co(II)-DMF interactions, having a definite configuration in spite of the bulkiness of the DMF molecule and its thermal movement in solution, are [17].c [18]. d [19].e Average values in crystals B and C. inferred to be attributed to the fairly strong and direc tional Co-O bond as well as the fairly rigid and pla nar structure of DMF.…”

Naturforsch. 50a, 301-306 (1995); received September 28, 1995 Dedicated to Prof. Hitoshi Ohtaki on the occasion of his 60th birthdayThe solvation structure of Co2+ in N,N-dimethylformamide (DMF) has been studied by X-ray diffraction measurements on cobalt (II) and magnesium (II) Perchlorate solutions of the same concen tration, using an isostructural substitution method. The radial distribution function revealed three distinct peaks assigned to the oxygen, amido carbon (CJ, and nitrogen atoms of six planar DMF molecules in the first coordination sphere around the metal atom. The distance from the cobalt atom to each atom (O, Cx, N) is 213,299, and 423 pm, respectively. This indicates that the Co-O-Cj bond angle is 122-123° and the metal atom is close to the O-Cj-N plane of the DMF molecule.

“…(7)° -179.6(7)°] show that the boron is approximatively coplanar with each amide plane and in the lone-pair direction of each carbonyl group (trans to the Ν atom). A slight deviation of these angles from the idealized values (120° and 180°) may be an indication of small steric effects due to the crowded coordination structure [5]. In the formamide radical, the O-C bonds [1.288 (9) …”

We present an in situ small- and wide-angle X-ray scattering (SAXS/WAXS) and quick-scanning extended X-ray absorption fine-structure (QEXAFS) spectroscopy study on the crystallization of the metal-organic framework ZIF-7. In combination with DFT calculations, the self-assembly and growth of ZIF-7 microrods together with the chemical function of the crystal growth modulator (diethylamine) are revealed at all relevant length scales, from the atomic to the full crystal size.
